Liquid water flows isothermally at 20°C through a one-inlet, one-exit duct operating at steady state. The duct’s inlet and exit diameters are 0.02 m and 0.1 m, respectively. At the inlet, the velocity is 10 m/s and pressure is 1 bar. At the exit, determine the mass flow rate, in kg/s, and velocity, in m/s.
The continuity equation allows finding the results for the speed and flow of the outlet pipe are:
Q = 3.14 kg / s v₂ = 0.4 m / s
Fluid mechanics studies the movement and fluid dynamics, it is described by two fundamental relationships:
The Bernoulli equation that an expression of the energy conservation\(P_1 + \frac{1}{2} \rho v_1^2 + \rho g y_1 = P_2 + \frac{1}{2} \rho v_2^2 + \rho g y_2\)
Where P is the pressure, v the velocity, y the height, the subscripts are two selected points of interest in the pipe.
The continuity equation which is an expression that our principle of mass conservation for fluids
\(A_1v_1 = A_2 v_2\)
Where A₁ and A₂ is the area of the inlet and outlet pipes and v₁ and v₂ are the velocities of the fluid at the inlet and outlet
They indicate the inlet and outlet diameters of the pipe are d₁ = 0.02 m and d₂ = 0.1 m, the inlet velocity v₁ = 10 m / s, with the continuity equation let's find the outlet velocity
\(v_2 = ( \frac{A_1}{A_2} )^2 \ v_1\)
the cross section of the tavern is
A = \(\pi r^2 = \pi \ d^2/4\)
Where r is the radius and d is the diameter
Let's substitutes
\(v_2 = (\frac{d_1}{d_2} )^2 \ v_1\)
\(v_2 = (\frac{0.02}{0.1} )^2 \ 10\)
v₂ = 0.4 m / s
The flow (Q) is defined as the amount of liquid that passes through the section of the pipe per unit of time, we can see that this is the same conservation of mass, therefore
Q = A v
Q = \(\pi \frac{d_2^2}{4} \ v_2\)π d2 ^ 2 v2
Q = \(\pi \ \frac{0.1^2}{4} \ 0.4\)
Q = 3.14 10⁻³ m ^ 3 / s
As the transported liquid is water
1 liter water = 1 kg
Consequently
1 m³ = 1000 liter = 1000 kg of water
Let's reduce the flow
Q = 3.14 10⁻³ m³/s ( \(\frac{10^3 kg}{1 m^3}\) )
Q = 3.14 kg / s
In conclusion using the continuity equation we can find the results for the speed and flow of the outlet pipe are:
v₂ = 0.4 m / s Q = 3.14 kg / s

Solvent n-Heptane Cyclohexane Benzene Chloroform Acetone Molar volume (cm' mol-1) Solubility parameter 8 (MPa1/2) 195.9 15.1 108.5 16.8 29.4 18.6 80.7 19.0 74.0 20.3 (ii) Which solvent is closest to the athermal limit for each polymer (i.e., which is the best solvent)?
Based on the solubility parameters, Acetone (with a solubility parameter of 19.0 MPa1/2) is the only solvent that falls within the range of both PDMS and PS. Therefore, acetone is capable of dissolving both PDMS and PS at room temperature.
To determine which solvent is closest to the athermal limit for each polymer, we need to compare the solubility parameter of each solvent to the square root of the cohesive energy density (CED) of each polymer. The athermal limit is defined as the solvent that has a solubility parameter closest to the square root of the CED of the polymer.
The square root of the CED for PDMS is 6.57 MPa1/2, and the closest solvent in the table is Cyclohexane (with a solubility parameter of 15.1 MPa1/2). Therefore, Cyclohexane is the best solvent for PDMS.
The square root of the CED for PS is 6.85 MPa1/2, and the closest solvent in the table is Chloroform (with a solubility parameter of 16.8 MPa1/2). Therefore, Chloroform is the best solvent for PS.

Race cars at the Indianapolis Speedway average speeds of 185 mi/h. After determining the altitude of Indianapolis, find the Mach number of these cars and estimate whether compressibility might affect their aerodynamics.
Answer:
- the Mach number is 0.24.
- Compressibility becomes effective when Mach number is greater than 0.3, the Mach number of the race cars is less than 0.3, hence, compressibility will not affect their aerodynamics.
Explanation:
Given the data in the question;
Average speed V = 185 miles per hour = ( 185 /2.237 ) m/s = 82.7 m/s
From Almanac, we can find that Indianapolis is at 220 m altitude.
So from table, at that altitude, the standard speed of sound will be 339.4 m/s .
Mach number of the race car will be;
Mach Number = Velocity / sound speed
we substitute
Mach Number = ( 82.7 m/s ) / ( 339.4 m/s )
Mach Number = 0.24
Therefore the Mach number is 0.24.
We know that, compressibility becomes effective when the Mach number is greater than 0.3.
Since the Mach number of the race cars is less than 0.3, compressibility will not affect their aerodynamics.
determine the fatigue strength sy of an aisi 1020 hot-rolled steel rotating beam specimen with fit : 55 kpsi corresponding to a life of 12,500 cycles of stress reversal. also determine the fatigue life for a reversed stress amplitude of 36 kpsi.
The fatigue strength (Sy) of the AISI 1020 hot-rolled steel rotating beam specimen is 55 kpsi for 12,500 cycles of stress reversal. The fatigue life for a reversed stress amplitude of 36 kpsi cannot be determined without knowing the ultimate tensile strength (Sut) of the material.
To determine the fatigue strength and fatigue life of an AISI 1020 hot-rolled steel rotating beam specimen, we can use the Goodman diagram. The Goodman diagram relates the mean stress and the alternating stress to the fatigue strength of a material.
First, let's determine the fatigue strength (S_y) of the material corresponding to a life of 12,500 cycles of stress reversal using the given data:
Given:
Stress amplitude (S_a) = 55 kpsi
Number of cycles (N) = 12,500
From the Goodman diagram, we can determine the fatigue strength (S_y) using the following equation:
1/S_y = (1/S_e) + (1/S_ut)*(S_a/S_ut)
Where:
S_e = Endurance limit (fatigue strength for infinite life)
S_ut = Ultimate tensile strength
Typically, the endurance limit of AISI 1020 steel is estimated to be around 0.5*S_ut. Considering this, we can rearrange the equation to solve for S_y:
1/S_y = (2/N)*(S_a/S_ut)
Substituting the given values:
1/S_y = (2/12,500)*(55 kpsi)/(S_ut)
Assuming S_ut is the ultimate tensile strength of AISI 1020 steel, you would need to provide that value to proceed with the calculation. Once you provide the value of S_ut, I can calculate the fatigue strength (S_y) for you.
Similarly, we can determine the fatigue life for a reversed stress amplitude of 36 kpsi. Again, we'll use the Goodman diagram and the same equation:
1/S_y = (2/N)*(S_a/S_ut)
Substituting the given values:
1/S_y = (2/12,500)*(36 kpsi)/(S_ut)
Once you provide the value of S_ut, I can calculate the fatigue life for a stress amplitude of 36 kpsi.

If the acceleration of the particle is defined by the relation a = -0.5 v3/2, where a in m/s2 and v in m/s. Determine a) the distance the particle will have traveled when its velocity is 5 m/s b) the time when v = 1m/s c) the time require for the particle to travel 8m
Answer:
a) 3.5 m
b) 14 secs
c) 1.4 secs
Explanation:
a) Determine the distance the particle will travel
given velocity ( final velocity ) = 5 m/s
v^2 = u^2 + 2as
s = ( v^2 - u^2 ) / 2a
= ( 5^2 - 8^2 ) / 2 ( -0.5 * 5^3/2 )
= 3.5 m
b) Determine the time when v = 1m/s
V = u + at
1 = 8 + ( -0.5 * 1^3/2 ) * t
∴ t = 14 secs
c) Determine the time required for particle to travel 8 m
we will employ both equations above
V^2 = u^2 + 2as
s = 8 m , V = unknown , u = 8 m/s back to equation
V^2 = 8^2 + 2 ( - 1/2 * V^3/2 ) * 8
∴ V^2 + 8V^3/2 - 64 = 0
resolving the above equation
V = 3.478 m/s
now using the second equation
V = u + at
3.478 = 8 + ( - 1/2 * 3.478^3/2 ) * t
hence : t = 1.4 secs

always leave extra space in front of you when
Always leave extra space in front of you when driving, especially in situations where you may need to make sudden stops or take evasive action.
The importance of leaving extra space in front of your vehicle stems from the fact that doing so gives you more time to react to unforeseen events on the road, such as a sudden stop by the vehicle in front of you, an impediment in the road, or a person crossing the street. This extra space also acts as a cushion of safety in case you have to swerve or stop quickly to avoid a collision.
How much extra space you should leave in front of your car depends on many factors, including your speed, the condition of the road, the weather, and the volume of traffic. It is frequently recommended to keep a two-second following distance or greater in good conditions. This means that you must follow the vehicle in front of you by at least two seconds, counting the time it takes for the vehicle to pass a set position and ensuring sure that you do not pass the same area before the vehicle does so.

This question is incomplete, the complete question is;
An air-standard Diesel cycle engine operates as follows: The temperatures at the beginning and end of the compression stroke are 30 °C and 700 °C, respectively. The net work per cycle is 590.1 kJ/kg, and the heat transfer input per cycle is 925 kJ/kg. Determine the a) compression ratio, b) maximum temperature of the cycle, and c) the cutoff ratio, v3/v2.
Use the cold air standard assumptions.
Answer:
a) The compression ratio is 18.48
b) The maximum temperature of the cycle is 1893.4 K
c) The cutoff ratio, v₃/v₂ is 1.946
Explanation:
Given the data in the question;
Temperature at the start of a compression T₁ = 30°C = (30 + 273) = 303 K
Temperature at the end of a compression T₂ = 700°C = (700 + 273) = 973 K
Net work per cycle \(W_{net\) = 590.1 kJ/kg
Heat transfer input per cycle Qs = 925 kJ/kg
a) compression ratio;
As illustrated in the diagram below, 1 - 2 is adiabatic compression;
so,
Tγ\(^{Y-1\) = constant { For Air, γ = 1.4 }
hence;
⇒ V₁ / V₂ = \((\) T₂ / T₁ \()^{\frac{1}{Y-1}\)
so we substitute
⇒ V₁ / V₂ = \((\) 973 K / 303 K \()^{\frac{1}{1.4-1}\)
= \((\) 3.21122 \()^{\frac{1}{0.4}\)
= 18.4788 ≈ 18.48
Therefore, The compression ratio is 18.48
b) maximum temperature of the cycle
We know that for Air, Cp = 1.005 kJ/kgK
Now,
Heat transfer input per cycle Qs = Cp( T₃ - T₂ )
we substitute
925 = 1.005( T₃ - 700 )
( T₃ - 700 ) = 925 / 1.005
( T₃ - 700 ) = 920.398
T₃ = 920.398 + 700
T₃ = 1620.398 °C
T₃ = ( 1620.398 + 273 ) K
T₃ = 1893.396 K ≈ 1893.4 K
Therefore, The maximum temperature of the cycle is 1893.4 K
c) the cutoff ratio, v₃/v₂;
Since pressure is constant, V ∝ T
So,
cutoff ratio S = v₃ / v₂ = T₃ / T₂
we substitute
cutoff ratio S = 1893.396 K / 973 K
cutoff ratio S = 1.9459 ≈ 1.946
Therefore, the cutoff ratio, v₃/v₂ is 1.946
