Answer:

The efficiency of the engine is 22.5%.

Explanation:

Efficiency = power output ÷ power input

power output = 55 kW

power input = specific energy×volumetric flow rate×density

specific energy = 44,000 kJ/kg

volumetric flow rate = 27.4 L/h = 27.4 L/h × 1000 cm^3/1 L × 1 h/3600 s = 7.61 cm^3/s

density = 0.73 g/cm^3 = 0.73 g/cm^3 × 1 kg/1000g = 7.3×10^-4 kg/cm^3

power input = 44,000 kJ/kg × 7.61 cm^3/s × 7.3×10^-4 kg/cm^3 = 244.4332 kJ/s = 244.4332 kW

Efficiency = 55 ÷ 244.4332 = 0.225 × 100 = 22.5%

**Answer:**

D) AND gate.

**Explanation:**

Given that:

A certain printer requires that all of the following conditions be satisfied before it will send a HIGH to la microprocessor acknowledging that it is ready to print

These conditions are:

1. The printer's electronic circuits must be energized.

2. Paper must be loaded and ready to advance.

3. The printer must be "on line" with the microprocessor.

Now; if these conditions are met the logic gate produces a HIGH output indicating readiness to print.

The objective here is to determine the basic logic gate used in this circuit.

Now;

For NOR gate;

NOR gate gives HIGH only when all the inputs are low. but the question states it that **"a HIGH is generated and applied to a 3-input logic gate". ** This already falsify NOR gate to be the right answer.

For NOT gate.

NOT gate operates with only one input and one output device but here; we are dealing with 3-input logic gate.

Similarly, OR gate gives output as a high if any one of the input signals is high but we need **"a HIGH that is generated and applied to a 3-input logic gate". **

Finally, AND gate output is HIGH only when all the input signal is HIGH and vice versa, i.e AND gate output is LOW only when all the input signal is LOW. So AND gate satisfies the given criteria that; all the three conditions must be true for the final signal to be HIGH.

**Answer:**

L = 75.25 mm

**Explanation:**

First we need to find the lateral strain:

**Lateral Strain = Change in Diameter/Original Diameter**

**Lateral Strain = (20.025 mm - 20 mm)/20 mm**

**Lateral Strain = 1.25 x 10⁻³**

Now, we will find the Poisson's Ratio:

**Poisson's Ratio = (E/2G) - 1 **

where,

E = Elastic Modulus = 105 GPa

G = Shear Modulus = 39.7 GPa

Therefore,

**Poisson's Ratio = [(105 GPa)/(2)(39.7 GPa)] - 1**

**Poisson's Ratio = 0.322**

Now, we find longitudinal strain by following formula:

**Poisson's Ratio = - Lateral Strain/Longitudinal Strain**

**Longitudinal Strain = - Lateral Strain/Poisson's Ratio**

**Longitudinal Strain = - (1.25 x 10⁻³)/0.322**

**Longitudinal Strain = - 3.87 x 10⁻³**

Now, we can fin the original length:

**Longitudinal Strain = Change in Length/L**

where,

L = Original Length = ?

Therefore,

**- 3.87 x 10⁻³ = (74.96 mm - L)/L**

**(- 3.87 x 10⁻³)(L) + L = 74.96 mm**

**0.99612 L = 74.96 mm**

**L = 74.96 mm/0.99612**

**L = 75.25 mm**

**Answer:**

The answer is below

**Explanation:**

A 4-pole, 3-phase induction motor operates from a supply whose frequency is 60 Hz. calculate: 1- the speed at which the magnetic field of the stator is rotating. 2- the speed of the rotor when the slip is 0.05. 3- the frequency of the rotor currents when the slip is 0.04. 4- the frequency of the rotor currents at standstill.

Given that:

number of poles (p) = 4, frequency (f) = 60 Hz

1) The synchronous speed of the motor is the speed at which the magnetic field of the stator is rotating. It is given as:

2) The slip (s) = 0.05

The speed of the motor (n) is the speed of the rotor, it is given as:

3) s = 0.04

The rotor frequency is the product of the supply frequency and slip it is given as:

4) At standstill, the motor speed is zero hence the slip = 1:

The rotor frequency is the product of the supply frequency and slip it is given as:

**Answer:**

I = Line Current = 242.58 A

Q = Reactive Power = 41.5 kVAr

**Explanation:**

Firstly, converting 100 hp to kW.

Since, 1 hp = 0.746 kW,

100 hp = 0.746 kW x 100

**100 hp = 74.6 kW**

**The power of a three phase induction motor can be given as:**

where,

P in = Input Power required by the motor

V = Line Voltage

I = Line Current

Cosα = Power Factor

Now, calculating Pin:

**a) Calculating the line current:**

**b) Calculating Reactive Power:**

The reactive power can be calculated as:

Q = P tanα

where,

Q = Reactive power

P = Active Power

α = power factor angle

Since,
