  (ii) 0.4 A; 1.92 W

  (iii) 1,152 J

  (iv) 18Ω — maximum power transfer theorem

Explanation:

As seen by the load, the equivalent source impedance is ...

  10 Ω + (24 Ω || 12 Ω) = (10 +(24·12)/(24+12)) Ω = 18 Ω

The open-circuit voltage seen by the load is ...

  (36 V)(12/(24 +12)) = 12 V

The Thevenin's equivalent source seen by the load is 12 V in series with 18 Ω.

__

The load current is ...

  (12 V)/(18 Ω +12 Ω) = 12/30 A = 0.4 A . . . . load current

The load power is ...

  P = I^2·R = (0.4 A)^2·(12 Ω) = 1.92 W . . . . load power

__

10 minutes is 600 seconds. At the rate of 1.92 J/s, the electrical energy delivered is ...

  (600 s)(1.92 J/s) = 1,152 J

__

The load resistance that will draw maximum power is equal to the source resistance: 18 Ω. This is the conclusion of the Maximum Power Transfer theorem.

The power transferred to 18 Ω is ...

  ((12 V)/(18 Ω +18 Ω))^2·(18 Ω) = 144/72 W = 2 W

Answer:

the process capability index for the precision machining process is 0.667

Explanation:

Given the data in the question;

Lower Specification Limits LSL = 0.99 mm

Upper Specification Limits USL = 1.01 mm.

The standard deviation σ = 0.005 mm

mean μ = 1 mm

capability index Cpk = ?

Cpk = min( USL - μ / 3σ, μ - LSL / 3σ )

we substitute

Cpk = min( 1.01 mm - 1 mm / 3(0.005 mm ), 1 - 0.99 mm / 3(0.005 mm) )

Cpk = min( 0.01 mm / 0.015 mm, 0.01 mm / 0.015 mm )

Cpk = min( 0.6666, 0.6666 )

∴ Cpk = 0.6666 ≈ 0.667

Therefore, the process capability index for the precision machining process is 0.667

(a) The active part of the inflow expands its cross-section as it passes the tidal turbine due to conservation of mass and energy.

(b) Several reasons contribute to the theoretical maximum efficiency not being achieved in practical tidal turbine deployments, including turbulence, non-uniform flow, and mechanical losses.

(c) Estimating the total fluid loading on the Alstom 1.4 MW OceadeTM turbine requires considering the flow velocity, rotor and tower dimensions, and making assumptions about the flow characteristics and structural properties.

(d) The estimates of forces obtained from the fluid loading calculations are essential for designing the turbine and tower structure by ensuring that they can withstand the anticipated loads and stresses.

(a) The active part of the inflow expands its cross-section as it passes the tidal turbine due to the principle of conservation of mass and energy. As the tidal flow encounters the turbine rotor, some of the kinetic energy of the flow is converted into mechanical energy to drive the turbine. To satisfy the conservation of mass, the cross-sectional area of the flow must increase to compensate for the reduction in flow velocity caused by energy extraction.

(b) Achieving the theoretical maximum efficiency in practical tidal turbine deployments is challenging due to several reasons. First, tidal flows are often characterized by turbulence, which disrupts the uniformity of the flow and reduces overall efficiency. Second, tidal flow itself is not uniformly distributed, and the flow characteristics vary with tidal cycles, further impacting efficiency. Lastly, mechanical losses in the turbine's components, such as friction and resistance, reduce the efficiency of energy conversion.

(c) Estimating the total fluid loading on the Alstom 1.4 MW OceadeTM turbine involves considering the flow velocity, rotor diameter, and tower dimensions. Assuming a tidal flow velocity of 3 m/s, the fluid loading can be estimated by considering the momentum change and forces acting on the rotor and tower surfaces. Assumptions may include a simplified flow model, neglecting factors such as turbulence and non-uniform flow, and assuming a stationary tower. These assumptions simplify the calculation while providing a reasonable estimate of the fluid loading.

(d) The estimates of forces obtained from the fluid loading calculations are crucial for designing the turbine and tower structure. These estimates help engineers determine the required structural strength, material selection, and design considerations to ensure that the turbine and tower can withstand the anticipated fluid forces and mechanical stresses. By considering the estimated forces, designers can optimize the structural integrity, stability, and reliability of the turbine and tower, ensuring safe and efficient operation in tidal environments.

Explanation:

This question is incomplete, the missing diagram is uploaded along this answer below.

Answer:

the forces required to keep the artery in place is 1.65 N

Explanation:

Given the data in the question;

Inlet velocity V₁ = 50 cm/s = 0.5 m/s

diameter d₁ = 15 mm = 0.015 m

radius r₁ = 0.0075 m

diameter d₂ = 11 mm = 0.011 m

radius r₂ = 0.0055 m

A₁ = πr² = 3.14( 0.0075 )² =  1.76625 × 10⁻⁴ m²

A₂ = πr² = 3.14( 0.0055 )² =  9.4985 × 10⁻⁵ m²

pressure at inlet P₁ = 110 mm of Hg = 14665.5 pascal

pressure at outlet P₂ = 95 mm of Hg = 12665.6 pascal

Inlet volumetric flowrate = A₁V₁ = 1.76625 × 10⁻⁴ × 0.5 = 8.83125 × 10⁻⁵ m³/s

given that; blood density is 1050 kg/m³

mass going in m' = 8.83125 × 10⁻⁵ m³/s × 1050 kg/m³ = 0.092728 kg/s

Now, using continuity equation

A₁V₁ = A₂V₂

V₂ = A₁V₁ / A₂ = (d₁/d₂)² × V₁

we substitute

V₂ =  (0.015 / 0.011 )² × 0.5

V₂ = 0.92975 m/s

from the diagram, force balance in x-direction;

0 - P₂A₂ × cos(60°) + Rₓ = m'( V₂cos(60°) - 0 )    

so we substitute in our values

0 - (12665.6 × 9.4985 × 10⁻⁵)  × cos(60°) + Rₓ = 0.092728( 0.92975 cos(60°) - 0 )    

0 - 0.6014925 + Rₓ =  0.043106929 - 0

Rₓ = 0.043106929 + 0.6014925

Rₓ = 0.6446 N

Also, we do the same force balance in y-direction;

P₁A₁ - P₂A₂ × sin(60°) + R\(_y\) = m'( V₂sin(60°) - 0.5 )  

we substitute

⇒ (14665.5 × 1.76625 × 10⁻⁴) - (12665.6 × 9.4985 × 10⁻⁵) × sin(60°) + R\(_y\) = 0.092728( 0.92975sin(60°) - 0.5 )

⇒ 1.5484 + R\(_y\) = 0.092728( 0.305187 )

⇒ 1.5484 + R\(_y\) = 0.028299    

R\(_y\) = 0.028299 - 1.5484

R\(_y\) = -1.52 N

Hence reaction force required will be;

R = √( Rₓ² + R\(_y\)² )

we substitute

R = √( (0.6446)² + (-1.52)² )

R = √( 0.41550916 + 2.3104 )

R = √( 2.72590916 )

R = 1.65 N

Therefore, the forces required to keep the artery in place is 1.65 N

The optimum angle of attack for a typical airfoil is about 4 degrees and during cruise, So the answer is C.

During cruise, the actual angle of attack will be closest to this optimum angle. This means that the plane will be flying efficiently and smoothly. However, if the angle of attack increases to 16 degrees, this can cause a stall..

A stall occurs when the airflow over the wings becomes disrupted and lift is no longer generated. This can lead to a loss of control and potentially dangerous situation.

Therefore, it is important for pilots to be aware of their angle of attack and to avoid exceeding the maximum limit during flight.

In summary, the optimum angle of attack for a typical airfoil is 4 degrees and during cruise, the actual angle of attack should be as close to this as possible to ensure safe and efficient flight. Hence, the answer is C.

Explanation:

The heat flux is =1038kW/m² , the heat lost per hour is =259.5 kW, the heat lost per hour using a sheet of soda- lime glass.

The thickness of steel( t) = 10mm = 10× 10^-³m

The temperature difference on both sides = 300-100

∆T = 200°C

But the formula for heat flux = q = k∆T/t

Where K = thermal conductivity for steel = 51.9W/mK.

Substitute the variables into the formula for heat flux;

q = 51.9 × 200/10 × 10-³

q = 10380 × 10³/10

q = 10380000/10

q = 1038000 W/m² = 1038kW/m²

If the museum is running short of funds, and you decide to increase revenue. An increase or decrease in the price of admission into the museum depends on the following:

1. If demand for admission into the museum is elastic there are two possible outcomes

a. An increase in the price of admission leads to a decrease in the quantity demand of admission into the museum

b. A decrease in price of admission into the museum leads to an increase in the quantity demand of admission into the museum.

This follows the law of demand which states that "the higher the price, the lower the quantity demanded and the lower the price, the higher the quantity demanded".

2. If the demand for admission into the museum is inelastic, then an increase in price will lead to an increase in revenue of the museum.

Therefore, before the curator increase the price of admission into the museum, he should first determine the price elasticity of demand of the museum.

Combining several class-C address ranges into a single network or route is possible using classless inter-domain routing (CIDR, also known as supernetting).

Class-C IP addresses are added as a result of this routing technique.

Internet service providers (ISPs) distribute these addresses for usage by their clients.

CIDR addresses can increase the number of IP addresses that are available to your company while reducing the size of your routing tables.

Previously, you had to enter a subnet mask that was either greater than or equal to the mask needed for the network class. The biggest subnet for class-C addresses that could be configured consisted of 253 hosts and was 255.255.255.0.

To fix maximum recursion depth exceeded in Python, you can: 1) Increase the recursion limit using sys.setrecursionlimit(limit), or 2) Implement a different, non-recursive algorithm.

Maximum recursion depth exceeded occurs when a function recursively calls itself too many times, and Python's default recursion limit is exceeded. To fix this issue, you can increase the recursion limit using the sys module by calling sys.setrecursionlimit(limit), where 'limit' is the new desired recursion depth.

However, increasing the recursion limit is generally discouraged as it may lead to memory issues. The recommended approach is to find an alternative, non-recursive algorithm or use tail recursion optimization, if possible. Always be cautious with recursion to avoid potential crashes or memory-related issues.

Answer:

Roll force, F = 5.6 MN

Explanation:

Sheet width, b = 0.5 m

Roll contact length, \(l_{p} = 40 mm\)

Strength coefficient, \(\sigma_{0} = 200 MPa\)

Thickness, h = 11 mm

Since the sheet of metal is cold worked by 40%, the reduction in thickness will be:

Δh = 40% * 11 = 0.4 * 11 = 4.4 mm

Strain, e = (Δh)/h

e = 4.4/11 = 0.4

The roll force is calculated by the formula:

\(F = \sigma_{f} l_{p} b\)

\(\sigma_{f} = \sigma_{0} (e+1)\\\sigma_{f} = 200 (0.4+1)\\\sigma_{f} = 200 *1.4\\\sigma_{f} = 280 MPa\)

Substituting the value of \(\sigma_{f}\), \(l_{p}\), and b into the formula for the roll force:

\(F = \sigma_{f} l_{p} b\\F = 280 * 0.04 * 0.5\\F = 5.6 MN\)

Answer:

11/12 Rev is required to completely close the bottle

Explanation:

Given the data in the question;

pitch = lead = 0.125 inch

total distance moved in 2.75 rotation = 0.125 in × 2.75

Now; Redesigned thread is three (3) start

lead = 3 × pitch = 3 × 0.125 inch

so

Number of turns required = total distance moved / distance moved in one rotation

Number of turns required = total distance / lead

we substitute

Number of turns required  = 0.125 in × 2.75 / 3 × 0.125 inch

= 2.75 / 3

= 275 / 300

reduce the numbers ( by dividing the numerator and denominator by 25 )

Number of turns required = 11/12 Rev

Therefore, 11/12 Rev is required to completely close the bottle
