[cu38, 8e] for a one-inlet, one-exit control volume at steady state, the mass flow rates at the inlet and exit are equal but the inlet and exit volumetric flow rates may not be equal.

Answers

Answer 1

For a one-inlet, one-exit control volume at steady state (cu38), the mass flow rates (m) at the inlet and exit are equal, but the inlet and exit volumetric flow rates (Q) may not be equal due to differences in fluid density (ρ) at the inlet and exit points.

Would you explain more about mass flow rates?

For a one-inlet, one-exit control volume at steady state (cu38), the mass flow rates (m) at the inlet and exit must be equal, as there is no accumulation or loss of mass within the control volume. This can be represented by the equation:

m_inlet = m_exit

However, the inlet and exit volumetric flow rates (Q) may not be equal, as the density (ρ) of the fluid can change between the inlet and exit points. Volumetric flow rate (Q) is related to mass flow rate (m) and density (ρ) by the equation:

Q = m / ρ

Since m_inlet = m_exit, but the density at the inlet (ρ_inlet) and exit (ρ_exit) may differ, we can express the relationship between the inlet and exit volumetric flow rates as:

Q_inlet = (m_inlet / ρ_inlet) ≠ (m_exit / ρ_exit) = Q_exit

An aircraft component is fabricated from an aluminum alloy that has a plane strain fracture toughness of 30 . It has been determined that fracture results at a stress of 237 MPa when the maximum (or critical) internal crack length is 2.78 mm. a) Determine the value of for this same component and alloy at a stress level of 355 MPa when the maximum internal crack length is 1.39 mm.

Answers

Answer:

fracture will occur since ( 31.8 Mpa√m ) is greater than the \(K_{Ic\) of the material ( 30 Mpa√m )

Explanation:

Given the data in the question;

To determine whether the aircraft component will fracture, given a fracture toughness of 30 Mpa√m, stress level of 355 and maximum internal crack length of 1.39 mm.

On a similar component, it has been said that fracture results at a stress of 237 MPa when the maximum (or critical) internal crack length is 2.78 mm.

so we first of all solve for the parameter Y in the condition where fracture occurred.

\(K_{Ic\) = 30 Mpa√m

σ = 237 MPa

2α = 2.78 mm = 2.78 × 10⁻³ m  

so

Y = \(K_{Ic\) / σ√πα

we substitute

Y = (30 Mpa√m) / (237 MPa)√(π(2.78 × 10⁻³ m / 2 ) )

Y =  (30 Mpa) / (237)( 0.06608187 )

Y = 30 / 15.6614

Y = 1.9155

Next we solve for Yσ√πα for the second case;

σ = 355 Mpa, 2α = 1.39 mm = 1.39 × 10⁻³ m

so

Yσ√πα = 1.9155 × 355 Mpa × √( π × (1.39 × 10⁻³ m / 2) )

= 1.9155 × 355 × 0.0467269

= 31.8 Mpa√m

so

( 31.8 Mpa√m ) > \(K_{Ic\) ( 30 Mpa√m )

Therefore, fracture will occur since ( 31.8 Mpa√m ) is greater than the \(K_{Ic\) of the material ( 30 Mpa√m )

cold air standard otto cycle has a compression ratio of 12. At the
beginning of compression, the pressure is 100KPa and temperature is
300K. The max temperature of cycle is 2600K. Evaluate specific

Answers

The specific heat ratio, also known as the isentropic exponent or adiabatic index, is a parameter used to evaluate thermodynamic processes. For a cold air standard Otto cycle, the specific heat ratio can be calculated based on the given information.

First, we need to determine the specific heat ratio, γ, of the air. For air, γ is approximately 1.4.

The compression ratio, r, is given as 12. This means that the final volume (V2) is equal to the initial volume (V1) divided by 12.

Using the ideal gas law, we can calculate the initial volume:
V1 = (n * R * T1) / P1
where n is the number of moles, R is the specific gas constant, T1 is the initial temperature, and P1 is the initial pressure.

Let's assume the number of moles is constant, so n = 1. The specific gas constant for air, R, is approximately 287 J/(kg*K).

Substituting the given values:
V1 = (1 * 287 * 300) / 100 = 861 m^3/kg

Now, we can calculate the final volume:
V2 = V1 / r = 861 / 12 = 71.75 m^3/kg

Next, we can calculate the specific heat ratio during compression, γc, using the relation:
γc = (V2 / V1)^(γ - 1)
γc = (71.75 / 861)^(1.4 - 1) = 0.6206

Since the cold air standard Otto cycle involves two constant volume processes (isochoric), the specific heat ratio during expansion, γe, is equal to the specific heat ratio during compression.

Therefore, the specific heat ratio for the cold air standard Otto cycle is 0.6206.

In conclusion, for the given cold air standard Otto cycle with a compression ratio of 12, an initial pressure of 100 KPa, an initial temperature of 300 K, and a maximum temperature of 2600 K, the specific heat ratio is approximately 0.6206. This value is crucial for analyzing and understanding the thermodynamic behavior of the cycle, including the compression and expansion processes

The bar of a pry bar acts as a ________ to multiply the amount of force that can be applied.
Select one:
A. ratchet
B. lever
C. pivot
D. fulcrum

Answers

The bar of a pry bar acts as a lever to multiply the amount of force that can be applied.

A lever is a simple machine consisting of a rigid bar that can rotate around a fixed point called a fulcrum. The lever allows for the amplification of force by using a mechanical advantage.

In the case of a pry bar, the fulcrum is the point where the bar is positioned or supported. When force is applied to one end of the bar, known as the effort or input force, it creates a turning effect around the fulcrum. This turning effect generates a force on the other end of the bar, known as the load or output force, enabling the user to exert a greater force than what was initially applied.

The key principle behind the lever is that it allows the redistribution of force. By increasing the distance between the point of application of the input force and the fulcrum, a smaller input force can generate a larger output force. This principle is known as leverage.

The longer the bar of the pry bar, the greater the leverage and mechanical advantage. The mechanical advantage of a lever is calculated by dividing the distance from the fulcrum to the point of application of the input force (effort arm) by the distance from the fulcrum to the point of application of the output force (load arm). A larger mechanical advantage means that a smaller input force can produce a proportionally larger output force.

Thus, the correct option is "b".

A 35kg block of mass is subjected to forces F1=100N and F2=75N at agive angle thetha= 20° and 35° respectively.find the distance it slides in 10seconds if the kinetic coefficient is 0.4.

Answers

Answer:

21 m

Explanation:

Since F₁ = 100 N and acts at an angle of 20° to the horizontal, it has horizontal component F₁' = 100cos20° = 93.97 N and vertical component F₁" = 100sin20° = 34.2 N.

Also, F₂ = 75 N and acts at an angle of -35° to the horizontal, it has horizontal component F₂' = 75cos(-35°) = 75cos35° = 61.44 N and vertical component F₂" = 75sin(-35°) = -75sin35° = -43.02 N

The resultant horizontal force F₃' = F₁' + F₂' = 93.97 N + 61.44 N = 155.41 N

The resultant vertical force F₃" = F₁" + F₂" = 34.2 N - 43.02 N = -8.82 N

If f is the frictional force on the block, the net horizontal force on the block is F = F₃' - f.

Since f = μN where μ = coefficient of kinetic friction = 0.4 and N = normal force on the block.

For the block to be in contact with the surface, the vertical forces on the block must balance.

Since the normal force, N must equal the resultant vertical force F₃" and the weight, W = mg of the object for a zero net vertical force,

N = mg + F₃" (since both the weight and the resultant vertical force act downwards)

N = mg + F₃"

Since m = mass of block = 35 kg and g = acceleration due to gravity = 9.8 m/s² and F₃" = 8.82 N

So,

N = mg + F₃"

N = 35 kg × 9.8 m/s² + 8.82 N

N = 343 N + 8.82 N

N = 351.82 N

So, the net horizontal force F = F₃' - f.

F = 155.41 N - 0.4 × 351.82 N

F = 155.41 N - 140.728 N

F = 14.682 N

Since F = ma, where a = acceleration of block,

a = F/m = 14.682 N/35 kg = 0.42 m/s²

To find the distance the block moved, x we use the equation

x = ut + 1/2at² where u = initial speed of block = 0 m/s, t = time = 10 s and a = acceleration of block = 0.42 m/s²

Substituting the values of the variables into the equation, we have

x = ut + 1/2at²

x = 0 m/s × 10 s + 1/2 × 0.42 m/s² × (10 s)²

x = 0 m + 1/2 × 0.42 m/s² × 100 s²

x = 0.21 m/s² × 100 s²

x = 21 m

So, the distance moved by the block is 21 m.

A lake with a surface area of 525 acres was monitored over a period of time. During onemonth period the inflow was 30 cfs (ie. ft3 /sec), the outflow was 27 cfs, and a 1.5 in seepage loss was measured. During the same month, the total precipitation was 4.25 inches. Evaporation loss was estimated as 6 inches. Estimate the storage change for this lake during the month.

Answers

Answer:

The storage of the lake has increased in \(4.58\times 10^{6}\) cubic feet during the month.

Explanation:

We must estimate the monthly storage change of the lake by considering inflows, outflows, seepage and evaporation losses and precipitation. That is:

\(\Delta V_{storage} = V_{inflow} -V_{outflow}-V_{seepage}-V_{evaporation}+V_{precipitation}\)

Where \(\Delta V_{storage}\) is the monthly storage change of the lake, measured in cubic feet.

Monthly inflow

\(V_{inflow} = \left(30\,\frac{ft^{3}}{s} \right)\cdot \left(3600\,\frac{s}{h} \right)\cdot \left(24\,\frac{h}{day} \right)\cdot (30\,days)\)

\(V_{inflow} = 77.76\times 10^{6}\,ft^{3}\)

Monthly outflow

\(V_{outflow} = \left(27\,\frac{ft^{3}}{s} \right)\cdot \left(3600\,\frac{s}{h} \right)\cdot \left(24\,\frac{h}{day} \right)\cdot (30\,days)\)

\(V_{outflow} = 66.98\times 10^{6}\,ft^{3}\)

Seepage losses

\(V_{seepage} = s_{seepage}\cdot A_{lake}\)

Where:

\(s_{seepage}\) - Seepage length loss, measured in feet.

\(A_{lake}\) - Surface area of the lake, measured in square feet.

If we know that \(s_{seepage} = 1.5\,in\) and \(A_{lake} = 525\,acres\), then:

\(V_{seepage} = (1.5\,in)\cdot \left(\frac{1}{12}\,\frac{ft}{in} \right)\cdot (525\,acres)\cdot \left(43560\,\frac{ft^{2}}{acre} \right)\)

\(V_{seepage} = 2.86\times 10^{6}\,ft^{3}\)

Evaporation losses

\(V_{evaporation} = s_{evaporation}\cdot A_{lake}\)

Where:

\(s_{evaporation}\) - Evaporation length loss, measured in feet.

\(A_{lake}\) - Surface area of the lake, measured in square feet.

If we know that \(s_{evaporation} = 6\,in\) and \(A_{lake} = 525\,acres\), then:

\(V_{evaporation} = (6\,in)\cdot \left(\frac{1}{12}\,\frac{ft}{in} \right)\cdot (525\,acres)\cdot \left(43560\,\frac{ft^{2}}{acre} \right)\)

\(V_{evaporation} = 11.44\times 10^{6}\,ft^{3}\)

Precipitation

\(V_{precipitation} = s_{precipitation}\cdot A_{lake}\)

Where:

\(s_{precipitation}\) - Precipitation length gain, measured in feet.

\(A_{lake}\) - Surface area of the lake, measured in square feet.

If we know that \(s_{precipitation} = 4.25\,in\) and \(A_{lake} = 525\,acres\), then:

\(V_{precipitation} = (4.25\,in)\cdot \left(\frac{1}{12}\,\frac{ft}{in} \right)\cdot (525\,acres)\cdot \left(43560\,\frac{ft^{2}}{acre} \right)\)

\(V_{precipitation} = 8.10\times 10^{6}\,ft^{3}\)

Finally, we estimate the storage change of the lake during the month:

\(\Delta V_{storage} = 77.76\times 10^{6}\,ft^{3}-66.98\times 10^{6}\,ft^{3}-2.86\times 10^{6}\,ft^{3}-11.44\times 10^{6}\,ft^{3}+8.10\times 10^{6}\,ft^{3}\)

\(\Delta V_{storage} = 4.58\times 10^{6}\,ft^{3}\)

The storage of the lake has increased in \(4.58\times 10^{6}\) cubic feet during the month.

The volume of water gained and the loss of water through flow,

seepage, precipitation and evaporation gives the storage change.

Response:

The storage change for the lake in a month is 1,582,823.123 ft.³

How can the given information be used to calculate the storage change?

Given parameters:

Area of the lake = 525 acres

Inflow = 30 ft.³/s

Outflow = 27 ft.³/s

Seepage loss = 1.5 in. = 0.125 ft.

Total precipitation = 4.25 inches

Evaporator loss = 6 inches

Number of seconds in a month is found as follows;

\(30 \ days/month \times \dfrac{24 \ hours }{day} \times \dfrac{60 \, minutes}{Hour} \times \dfrac{60 \, seconds}{Minute} = 2592000 \, seconds\)

Number of seconds in a month = 2592000 s.

Volume change due to flow, \(V_{fl}\) = (30 ft.³/s - 27 ft.³/s) × 2592000 s = 7776000 ft.³

1 acre = 43560 ft.²

Therefore;

525 acres = 525 × 43560 ft.² =  2.2869 × 10⁷ ft.²

Volume of water in seepage loss, \(V_s\) = 0.125 ft. × 2.2869 × 10⁷ ft.² = 2,858,625 ft.³

Volume gained due to precipitation, \(V_p\) = 0.354167 ft. × 2.2869 × 10⁷ ft.² = 8,099,445.123 ft.³

Volume evaporation loss, \(V_e\) = 0.5 ft. × 2.2869 × 10⁷ ft.² = 11,434,500 ft.³

\(Storage \, change \, \Delta V = \mathbf{V_{fl} - V_s + V_p - V_e}\)

Which gives;

ΔV = 7776000 - 2858625 + 8099445.123 - 11434500 = 1582823.123

The storage change, ΔV = 1,582,823.123 ft.³

Answers

The first claim is accurate; a list is a collection with extra operations related to indexing and iteration. The list's elements can be accessed quickly and easily with the help of these operations, and it is also possible to iterate through the complete collection.

The second claim is untrue because the == operator, not the equals method, is used to retrieve an element from a collection. This is so because the == function compares object references, and lists are frequently implemented in memory as arrays. The third claim is untrue because the index-based add function of the ArrayList class adds elements to the list's end with a constant amortised time complexity of O(1), not O(N). The fourth claim -- a shot -- is accurate.

Answers

According to Marcia, identity status involves the dimensions of exploration and commitment.

In Erik Erikson's theory of psychosocial development, James Marcia expanded on the concept of identity formation and proposed four identity statuses: identity diffusion, identity foreclosure, identity moratorium, and identity achievement. Marcia believed that identity formation involves two key dimensions: exploration and commitment. Exploration refers to actively seeking out and considering different identity options, such as exploring different career paths or values. Commitment, on the other hand, involves making a personal investment in an identity choice and integrating it into one's sense of self. The interplay between exploration and commitment determines an individual's identity status and their progress toward developing a coherent and stable sense of identity.

An unconstrained 10mm thick plate of steel 100mm on a side with a 25mm diameter hole in the center is heated from 20 degrees C to 120 degrees C. The linear CTE is 12x10-6/⁰C. What is the final diameter of the hole

Answers

Answer:

The correct answer is "25.03 mm".

Explanation:

Given:

Thickness of plate,

= 10 mm

On a side,

= 100 mm

Diameter hole,

= 25 mm

Coefficient of thermal expansion,

CTE = \(12\times 10^{-6} /^{\circ} C\)

Now,

⇒ \(D_i\times (12\times 10^{-6}) \Delta \theta = \Delta D\)

=  \(25\times 12\times 10^{-6} \Delta \theta\)

= \(3\times 10^{-4} \Delta \theta\)

= \(3\times 10^{-2}\)

hence,

The final diameter of hole will be:

\(D_f=25.03 \ mm\)    

How large a force is required to accelerate a 1300 kg car from rest to a speed of 20 m/s in a distance of 80 m?

The Boeing 787 Dreamliner is billed to be 20% more fuel efficient than the comparable Boeing 767 and will fly at Mach 0.85. The midsize Boeing 767 has a range of 12,000 km, a fuel capacity of 90,000 L, and flies at Mach 0.80. For Boeing 787, assume the speed of sound is 700 mph and calculate the projected volumetric flow rate of fuel for each of the two Dreamliner engines in m3/s.

Answers

Answer:

the projected volumetric flow rate of fuel for each of the two Dreamliner engines is 0.005 m³/s

Explanation:

Given the data in the question;

First we determine the fuel economy of Boeing 767

Range = 12,000 km

fuel capacity = 90,000 L

so,  fuel economy of Boeing 767 will be

η\(_f\) = Range / fuel capacity

η\(_f\) = ( 12,000 km / 90000 L ) ( 1000m / 1 km) ( 3.7854 L/gal × 264.2 gal/m² )

η\(_f\)  = 133,347.024 m/m³

Now, Boeing 787 is 20% more fuel efficient than Boeing 767

so fuel economy of Boeing 787 will be;

⇒ (1 - 20%) × fuel economy of Boeing 767

⇒ (1 - 0.2) × 133,347.024 m/m³

⇒ 0.8 × 133,347.024 m/m³

⇒ 106,677.6 m/m³

Hence, fuel economy of Boeing 787 dream line engine is

⇒ 106,677.6 m/m³ / 2 = 53,338.8 m/m³

Next, we find the velocity of Boeing 787

\(V_{787\) = Mach number of 787 × speed of sound

given that; Mach number is 0.85 and speed of sound is 700 mph

we substitute

\(V_{787\) = (0.85 × 700 mph) × ( 1 hr / 3600 s ) × ( 1609 m / 1 mile )

\(V_{787\) = 265.9319 m/s

Now, to get the Volume flow rate for each dream liner engine { Boeing 787 };

Volumetric flow rate = velocity of flight / fuel economy

we substitute

= 265.9319 m/s / 53,338.8 m/m³

= 0.0049857 ≈ 0.005 m³/s

Therefore,  the projected volumetric flow rate of fuel for each of the two Dreamliner engines is 0.005 m³/s

What are you doing if you succumb to "overgeneralization" when analyzing data from metrics?

A. Using data that is too broad to capture specific meanings

B. Possessing too many types of data to perform a valid analysis

C. Using limited data in an attempt to support broad conclusions

D. Trying to use several measurements to gauge one aspect of a program

Answers

The action that should be taken if you succumb to "overgeneralization" when analyzing data from metric is C. Using limited data in an attempt to support broad conclusions.

The correct answer is C. Using limited data in an attempt to support broad conclusions. Overgeneralization occurs when data is insufficient to support the conclusion being drawn and only a limited amount of data is being used to support a broad conclusion.
When you succumb to "overgeneralization" when analyzing data from metrics, you are using a small sample size or limited data to make broad conclusions or generalizations. This can lead to inaccurate or misleading results, as the limited data may not be representative of the entire population or situation. It is important to use a large enough sample size and consider all relevant data when making conclusions from metrics.
