The magnitude of the complex impedance per phase in ohms is 0.61 ohms (rounded to two decimal places).

To find the complex impedance per phase in ohms, we can use the following formula:

\(Z = V^2 / S\)

where:

V = voltage per phase = 345 kV / sqrt(3) = 199.45 kV (assuming a balanced system)

S = apparent power per phase = 614 MVA / 3 = 204.67 MVA (assuming a balanced system)

The real power per phase is given by:

P = S * cos(phi) = 204.67 MW * 0.74 = 151.45 MW

The reactive power per phase is given by:

Q = S * sin(phi) = 204.67 MW * sin(arccos(0.74)) = 113.25 MVAr

The apparent impedance per phase is given by:

|Z| =

 \(V / \sqrt{3} * \sqrt{(P^2 + Q^2) }/ S \\\\= 199.45 kV / \sqrt{3} * \sqrt{((151.45 MW)^2 + (113.25 MV \ Ar)^2)} / 204.67 MVA\)

Answer:

D all of the above

Explanation:

because I said so

Solution :

As the plane is flying in the air, the force of weight is pulling the plane down. This force must be equal to the force of lift which is generated from the plane's translation true the air. Therefore, the next condition must be satisfied.

\($F_W= L $\)  ................. (i)

The lift force of the plane is given by :

\($L=C_V \frac{\rho}{2} V^2 A$\)

Since the weight force of the plane is given, from the condition (i), we also know the intensity of the lift force.

Therefore, we transform the lift force expression to derive the lift coefficient formula:

\($C_L=\frac{2L}{\rho V^2 A}$\)

\($C_L=\frac{2 \times 1700}{2.38 \times 10^{-3 }\times (167.2)^2 \times 178} $\)

\($C_L = 0.287$\)

Fourth-order Low Pass  Filter If the gain of both filters is set at 1.586, the voltage gain will be down 6 dB at the cutoff frequency. We can get a more flat response by choosing different values of voltage gain for both stages.

It is possible to create a 4th order low-pass filter with just one Op Amp. Due to the interconnected nature of all filter parameters, component tolerance sensitivity needs to be confirmed. The 4th order Sallen-Key topology is too sensitive to component tolerances, making it unsuitable for application.

To calculate the number of cycles to failure (Nf) for an aircraft inspection panel with a discovered crack, one uses Paris' Law.

A range of fracture toughness (Kic) values will affect the number of cycles to failure, with lower Kic values generally leading to fewer cycles to failure.

Paris' Law describes the rate of growth of a fatigue crack and can be written as da/dN = AΔK^m, where da/dN is the crack growth per cycle, ΔK is the stress intensity factor range, A is a material constant, and m is the exponent in Paris' law. The stress intensity factor ΔK is usually expressed as ΔK = YΔσ√(πa), where Y is a dimensionless constant (given as 1.12), Δσ is the stress range, and a is the crack length.

Answer: \(p_{B} - p_{A}\) = 28800 Pa or 28.8 kPa

Explanation: To determine the pressure of a liquid in a rotating tank,it is used:

p = \(\frac{p_{fluid}.w^{2}.r^{2} }{2}\) - γfluid . z + c

where:

\(p_{fluid}\) is the liquid's density

w is the angular velocity

r is the radius

γfluid.z is the pressure variation due to centrifugal force.

For this question, the difference between a point on the circumference and a point on the axis will be:

\(p_{B} - p_{A}\) = \(\frac{p_{fluid}.w^{2}.r_{B} ^{2} }{2}\) - γfluid.\(z_{B}\) - (\(\frac{p_{fluid}.w^{2}.r_{A} ^{2} }{2}\) - γfluid.\(z_{A}\))

\(p_{B} - p_{A}\) = \(\frac{p_{fluid}.w^{2}}{2} (r_B^{2} - r_A^{2} )\) - γfluid(\(z_{B}\) -\(z_{A}\))

Since there is no variation in the z-axis, z = 0 and that the density of oil is 0.9.10³kg/m³:

\(p_{B} - p_{A}\) = \(\frac{p_{fluid}.w^{2}}{2} (r_B^{2} - r_A^{2} )\)

\(p_{B} - p_{A} = \frac{0.9.10^3.40^2}{2}(0.2^2 - 0)\)

\(p_{B} - p_{A}\) = 28800

The difference in pressure between two points, one on the circumference and the other on the axis is \(p_{B} - p_{A}\) = 28800 Pa or 28.8 kPa

The external force (in KN ) that the single-acting cylinder can sustain while moving in the extending direction. 30.89 kN ≈ 30.84 kN.

When moving in the extending direction, the pressure at the piston's inlet is 7.85 bar while the external force that the single-acting cylinder can sustain is 30.84 kN.

Here is the solution: The length of the pipe is 20 m, and the diameter is 0.038 m. The internal cross-sectional area of the pipe, A = πd2/4 = 1.13 × 10-3 m2.Volumetric flow rate, Q = 0.0015 m3/s.

Velocity, v = Q/A = 1.33 m/s.

Kinematic viscosity, ν = 0.0001 m2/s, Specific gravity, SG = 0.9, and Density, ρ = SG × 1000 = 900 kg/m3.

Reynolds number, Re = (ρvD)/ν= 8863 (since Re > 4000, the flow is turbulent).

Pressure drop, Δp = f (L/D) (ρv2/2), where f is the Darcy friction factor.

Since the flow is turbulent, use the Colebrook-White equation to determine the friction factor: f = (-2) log10[(ε/D)/3.7 + (2.51/Re) √(D/ε)] Where ε is the pipe roughness, which is taken as 0.0015 mm (given), and D is the diameter of the pipe.

Substituting the values gives f = 0.032. By substituting these values, we get Δp = 2.38 bar. The outlet pressure is 5.5 bar. Therefore, the pressure at the inlet of the piston (in bar) while moving in the extending direction is: 5.5 bar + 2.38 bar = 7.88 bar ≈ 7.85 bar.

The force acting on the cylinder in the extending direction is: F = (P1 - P2) × A, where P1 is the pressure at the piston's inlet, P2 is the atmospheric pressure, and A is the piston's cross-sectional area.

Substituting the values gives: F = (7.85 × 105 - 1.013 × 105) × (π/4) × (0.2)2 = 30.89 kN ≈ 30.84 kN.

Explanation:

To solve this problem, we can use the equations and relationships of the ideal Otto cycle.

(a) The pressure at the end of the heat-addition process is approximately 4000 kPa, and the temperature is approximately 1500 K.

(b) The net work output is 400 kJ/kg.

(c) The thermal efficiency of the cycle is approximately 50%.

(d) The mean effective pressure is -500 kPa.

The Otto cycle consists of four processes: intake, compression, combustion, and exhaust. Given the compression ratio and initial conditions, we can calculate various parameters for the cycle.

Let's solve the problem step by step:

(a) To find the pressure and temperature at the end of the heat-addition process:

For the compression process:

Given compression ratio (r) = 8

Initial pressure (P1) = 95 kPa

Initial temperature (T1) = 27 °C

Using the compression ratio, we can find the final pressure (P2) and temperature (T2) after the compression process:

P2 = P1 * (r ^ (γ)) -- (1)

T2 = T1 * (r ^ (γ-1)) -- (2)

For the given problem, γ can be approximated as 1.4, which is the specific heat ratio for air.

Substituting the values into equations (1) and (2):

P2 = 95 kPa * (8 ^ (1.4)) ≈ 4000 kPa

T2 = 27 °C * (8 ^ (1.4 - 1)) ≈ 1500 K

Therefore, at the end of the heat-addition process, the pressure is approximately 4000 kPa and the temperature is approximately 1500 K.

b) The net work output:

The formula used: is W = Q1 - Q2, where Q2 is the heat rejected during the constant-volume heat-rejection process.

From the formula, the net work output W = Q1 - Q2 = (C_v)(T3 - T2) - (C_v)(T4 - T1), where T3 and T4 are the temperatures at the end of the constant-volume heat-rejection and at the end of the expansion processes, respectively.

Using the formula to find the temperature at the end of the expansion process:

p3/p4 = (V4/V3)^γ => V4/V3 = (p3/p4)^(1/γ) = (95/4000)^(1/1.4) = 0.2247,

where p3 is the pressure at the end of the constant-volume heat-rejection process.

Since V3 = V2 and V4 = V1,

p1V1^γ = p2V2^γ => p1V1 = p2V2 = p3V3 = p4V4 = Constant =>

V4 = V1 * (p1/p4)^(1/γ) = 0.125 * (4000/95)^(1/1.4) = 0.6002 m^3/kg

From the steam table at 1500 K, Specific volume, v3 = 1.134 m^3/kg

Thus, V4/V3 = 0.6002/1.134 = 0.5295

From steam table, at 95 kPa and T4, v4 = 0.0025 m^3/kg, C_v = 0.718 kJ/kg K

Thus, (C_v)(T4 - T1) = p1V1[(v4/v1)^γ - (v3/v1)^γ], where T1 = 27°C = 300 K, and v1 = 0.8594 m^3/kg.

Hence, (C_v)(T4 - T1) = 0.718 * (T4 - 300) = 300(0.8594/0.0025)^1.4[(0.5295)^1.4 - 1]

Solving for T4, we get T4 = 793.15 K.

Therefore, net work output, W = (C_v)(T3 - T2) - (C_v)(T4 - T1) = 0.718(1500 - 793.15) - 0.718(793.15 - 300) = 400 kJ/kg.

(c) The thermal efficiency (η) of the Otto cycle is given by the equation:

η = 1 - (1 / r ^ (γ-1))

Substituting the value of γ = 1.4 and the compression ratio r = 8, we can calculate the thermal efficiency:

η = 1 - (1 / 8 ^ (1.4 - 1)) ≈ 0.5 or 50%

Therefore, the thermal efficiency of the cycle is approximately 50%.

d) The mean effective pressure for the cycle:

The formula used: MEP = W_net / V_swept = W_net / (V1 - V2)

From the formula, MEP = W_net / V_swept = W_net / (V1 - V2) = 400 / (0.125 - 1) = -500 kPa

Therefore, the mean effective pressure for the cycle is -500 kPa.

In summary for an ideal Otto cycle,

(a) The pressure at the end of the heat-addition process is approximately 4000 kPa, and the temperature is approximately 1500 K.

(b) The net work output is 400 kJ/kg.

(c) The thermal efficiency of the cycle is approximately 50%.

(d) The mean effective pressure is -500 kPa.
