To measure the storage time of a p-n junction diode, follow these steps:

1) Build a circuit as shown in Figure 3 using a 1k2 resistor, a p-n junction diode, and other necessary components.

2) Set the function generator to generate a square wave with a 16V peak-to-peak amplitude, a 1kHz frequency, and zero offset.

3) Connect an oscilloscope to the circuit to display the waveform exhibiting the transient response, similar to Figure 5.1 (a) in your lab manual.

4) Measure the storage time 't' of the p-n junction diode using cursors on the oscilloscope.

5) Explain your observations: You may observe that the storage time is the interval during which the diode is in the process of switching from the conducting state to the non-conducting state. This time is essential for understanding the diode's behavior in fast-switching applications.

6) If you replace the p-n junction diode with a Schottky diode, you would expect a different response. Schottky diodes have a faster switching time and lower forward voltage drop compared to p-n junction diodes. Therefore, the storage time would be shorter, making it more suitable for high-frequency applications.

The work needed for the compression of an ideal gas in a single reversible and adiabatic compressor can be expressed in terms of the mass flow rate, initial pressure (P1), final pressure (P2), and initial temperature (T1).

a. When compressing an ideal gas in a single reversible and adiabatic compressor, the work required can be calculated using the equation: W = (m_dot * R * T1) * ln(P2/P1), where W is the work, m_dot is the mass flow rate, R is the gas constant, T1 is the initial temperature, and ln represents the natural logarithm. This expression takes into account the change in pressure and temperature during the compression process.

b. In a two-stage compression process, the work needed can be minimized by selecting an intermediate pressure (P*) between P1 and P2. The value of P* should be determined such that the compression process is done with minimum work. By optimizing the pressure ratio between the stages, the work required for each compression can be reduced. To calculate the specific value of P*, detailed calculations involving thermodynamic relationships and optimization techniques are required.

In summary, the work needed for compressing an ideal gas depends on factors such as the mass flow rate, initial and final pressures, and initial temperature. In a two-stage compression process, selecting the intermediate pressure (P*) carefully can help minimize the work required. Precise calculations and analysis are necessary to determine the specific value of P*.

Answer:

1) The exergy of destruction is approximately 456.93 kW

2) The reversible power output is approximately 5456.93 kW

Explanation:

1) The given parameters are;

P₁ = 8 MPa

T₁ = 500°C

From which we have;

s₁ = 6.727 kJ/(kg·K)

h₁ = 3399 kJ/kg

P₂ = 2 MPa

T₂ = 350°C

From which we have;

s₂ = 6.958 kJ/(kg·K)

h₂ = 3138 kJ/kg

P₃ = 2 MPa

T₃ = 500°C

From which we have;

s₃ = 7.434 kJ/(kg·K)

h₃ = 3468 kJ/kg

P₄ = 30 KPa

T₄ = 69.09 C (saturation temperature)

From which we have;

h₄ = \(h_{f4}\) + x₄×\(h_{fg}\) = 289.229 + 0.97*2335.32 = 2554.49 kJ/kg

s₄ =  \(s_{f4}\) + x₄×\(s_{fg}\) = 0.94394 + 0.97*6.8235 ≈ 7.563 kJ/(kg·K)

The exergy of destruction, \(\dot X_{dest}\), is given as follows;

\(\dot X_{dest}\) = T₀ × \(\dot S_{gen}\) = T₀ × \(\dot m\) × (s₄ + s₂ - s₁ - s₃)

\(\dot X_{dest}\) = T₀ × \(\dot W\)×(s₄ + s₂ - s₁ - s₃)/(h₁ + h₃ - h₂ - h₄)

∴ \(\dot X_{dest}\) = 298.15 × 5000 × (7.563 + 6.958 - 6.727 - 7.434)/(3399 + 3468 - 3138  - 2554.49) ≈ 456.93 kW

The exergy of destruction ≈ 456.93 kW

2) The reversible power output, \(\dot W_{rev}\) = \(\dot W_{}\) + \(\dot X_{dest}\) ≈ 5000 + 456.93 kW = 5456.93 kW

The reversible power output ≈ 5456.93 kW.

Answer:

100 kWh

Explanation:

Since the freezer has a rating of 500 watts and runs for 200 hours in a month, the energy consumption can be gotten by getting the product of the rating of the freezer in kilowatts and the amount of time the fridge is on per month.

The rating of the freezer = 500 watts = 0.5 kW, time = 200 h

Energy consumption = rating * time = 0.5 kW * 200 h

Energy consumption = 100 kWh

Therefore the refrigerator uses 100 kWh per month

Answer:

1) 4.41 * 10^-4 kw

2) 2.20 * 10^-4 kw

Explanation:

Given data:

Filter = 500 m^3/min

dust velocity = 3g/m^3

bag ; length = 3 m , diameter = 0.13 m

change in pressure = 1 kPa

efficiency = 60%

1) Calculate the Fan power

First :

Calculate the total dust loading = 3 * 500 = 1500 g

To determine the Fan power we will apply the relation

\(n_{o} = \frac{\frac{p}{eg*Q*h} }{1000}\)    = \(\frac{\frac{p}{(3*10^{-3})* 981*( 500/60) *3 } }{1000}\)

fan power ( \(n_{0}\) ) = 4.41 * 10^-4 kw

2) calculate power drawn

change in P = 6 atm = 6 * 10^5 pa

efficiency compressor = 50%

hence power drawn = 4.41 * 10^-4 kw  * 50% = 2.20 * 10^-4 kw

First step : Calculate for Enthalpy

h1 - hf = -3909.9 kJ/kg ( For saturated liquid nitrogen at 600 kPa )

h2- hg = -222.5 kJ/kg ( For saturated vapor nitrogen at 600 kPa )

second step : Calculate the rate of heat transfer in boiler

Q1-2 = m( h2 - h1 )  = 0.008( -222.5 -(-390.9) = 1.347 kW

step 3 : find the enthalpy of superheated Nitrogen at 600 Kpa and 280 K

from the super heated Nitrogen table

h3 = -20.1 kJ/kg

step 4 : calculate the rate of heat transfer in the super heater

Q2-3 = m ( h3 - h2 )

The function y²tan X y is not homogeneous. A homogeneous function is a function in which the value of the function is the same when the variables are multiplied by a constant.

In this case, the function y²tan X y is not the same when the variables are multiplied by a constant. For example, if we multiply x and y by 2, the value of the function becomes 4tan 4y, which is not the same as y²tan X y. The degree of a homogeneous function is the highest power of any variable in the function. In this case, the highest power of y in the function y²tan X y is 2, so the degree of the function is 2.

Therefore, the function y²tan X y is not homogeneous and its degree is 2.

1. TURN ON YOUR HAZARD/EMERGENCY LIGHTS

Turn on your hazard lights to warn other drivers as soon as you sense something's wrong. Keep them on until help arrives, recommends the National Motorists Association (NMA).

2. SLOW DOWN AND PULL OFF THE ROAD

Aim for the right shoulder of the road. Consumer reports recommends that you pull over to a safe, flat location that is as far away from moving traffic as possible.

3. TURN YOUR WHEELS AWAY FROM THE ROAD AND PUT ON THE EMERGENCY BRAKE

The California Department of Motor Vehicles (DMV) recommends pulling your emergency brake, sometimes called the parking brake. If you have to park on a hill or slope, turn the car's wheels away from the road to help prevent the care from rolling into traffic, says the California DMV.

4. STAY IN YOUR VEHICLE

If you're on a highway or crowded road, the Insurance Information Institute (III) recommends that you avoid getting out of your vehicle to look at the damage or fix a mechanical problem. If you need to get out of the car, get your vehicle to a safe place and make sure the road around you is completely clear. If you're stopped on the right-hand side of the road, get out through the passenger-side door.

5. BE VISIBLE

Once you're safely out of the vehicle, prop up your hood to let other drivers know they should proceed with caution. This will alert other drivers that you're broken down, according to the NMA.

6. SET UP FLARES OR TRIANGLES

Place flares or triangles with reflectors behind your car to alert other drivers to the location where you've stopped, says the III.

7. CALL FOR HELP

Call or use an app to get a tow truck, mechanic or roadside assistance to come help. your insurance company or other provider who may be able to help. If you're in an emergency situation or are not sure who to contact, call 911 or the local police for help.
