T/F : Changing the value of the Enabled property of an object in code statements can be used to make an object appear on the form during program execution.

Answers

Answer 1

Changing the value of the Enabled property of an object in code statements affects its interactivity, not its visibility. To make an object appear or disappear on the form during program execution, you should change the value of the Visible property instead.

True. By setting the Enabled property of an object to True in code statements, you can make it visible and usable during program execution. However, it's important to note that the Enabled property only controls the ability of the user to interact with the object, and not its visibility on the form. To make an object appear on the form, you would need to set its Visible property to True.

Determine the gage pressure at the center of pipe A in pounds per square inch and

in kilopascals.

Answers

Answer: the stress is 384 pounds per square inch.

Step-by-step explanation:

Let S represent the stress in the material of the pipe.

Let P represent internal pressure of the pipe.

Let D represent internal diameter of the pipe.

Let T represent the thickness of the pipe.

The stress in the material of a pipe subject to internal pressure varies jointly with the internal pressure and the internal diameter of the pipe and inversely with the thickness of the pipe. Introducing a constant of proportionality, k, the expression becomes

S = kPD/T

The stress is 100 pounds per square inch when the diameter is 5 inches, the thickness is 0.75 inch, and the internal pressure is 25 pounds per square inch. It means that

100 = (k × 25 × 5)/0.75

125k = 100 × 0.75 = 75

k = 75/125 = 0.6

The equation representing the relationship becomes

S = 0.6PD/T

If the internal pressure is 40 pounds per square inch, the diameter is 8 inches and the thickness is 0.50 inch, then the stress would be

S = (0.6 × 40 × 8)/0.5

S = 384

Steam at 4 MPa and 350°C is expanded in an adiabatic turbine to 125kPa. What is the isentropic efficiency (percent) of this turbine if the steam is exhausted as a saturated vapor?

Answers

Answer:

\(\eta_{turbine} = 0.603 = 60.3\%\)

Explanation:

First, we will find actual properties at given inlet and outlet states by the use of steam tables:

AT INLET:

At 4MPa and 350°C, from the superheated table:

h₁ = 3093.3 KJ/kg

s₁ = 6.5843 KJ/kg.K

AT OUTLET:

At P₂ = 125 KPa and steam is saturated in  vapor state:

h₂ = \(h_{g\ at\ 125KPa}\) = 2684.9 KJ/kg

Now, for the isentropic enthalpy, we have:

P₂ = 125 KPa and s₂ = s₁ = 6.5843 KJ/kg.K

Since s₂ is less than \(s_g\) and greater than \(s_f\) at 125 KPa. Therefore, the steam is in a saturated mixture state. So:

\(x = \frac{s_2-s_f}{s_{fg}} \\\\x = \frac{6.5843\ KJ/kg.K - 1.3741\ KJ/kg.K}{5.91\ KJ/kg.K}\\\\x = 0.88\)

Now, we will find \(h_{2s}\)(enthalpy at the outlet for the isentropic process):

\(h_{2s} = h_{f\ at\ 125KPa}+xh_{fg\ at\ 125KPa}\\\\h_{2s} = 444.36\ KJ/kg + (0.88)(2240.6\ KJ/kg)\\h_{2s} = 2416.088\ KJ/kg\)

Now, the isentropic efficiency of the turbine can be given as follows:

\(\eta_{turbine} = \frac{h_1-h_2}{h_1-h_{2s}}\\\\\eta_{turbine} = \frac{3093.3\ KJ/kg-2684.9\ KJ/kg}{3093.3\ KJ/kg-2416.088\ KJ/kg}\\\\\eta_{turbine} = \frac{408.4\ KJ/kg}{677.212\ KJ/kg}\\\\\eta_{turbine} = 0.603 = 60.3\%\)

The correct answer is a. brittle deformation. therefore the correct option is (a) option.

Brittle deformation is when rocks fail as rigid solids. The rocks will break, rather than bend, under these conditions to produce fractures. Brittle deformation occurs along discrete planes in the rock instead of involving the rock body as a whole.Brittle materials include glass, ceramic, graphite, and some alloys with extremely low plasticity, in which cracks can initiate without plastic deformation and can soon evolve into brittle breakage.

A gas turbine power station operates on the simple Brighton cycle using air as an operating barrier. Air enters the turbine at 1MPa and 1000K and exits from it at 125kPa and 600K, and heat is expelled to the surrounding environment at a time rate of 7922kJ/s. Air flows through the cycle at a time rate of 2.5kg/s. Assuming that the compressor is the isotropy find the net power produced by the station.​

Answers

To determine the net power produced by the gas turbine power station, we need to calculate the work done by the turbine and the work done by the compressor. The net power produced is the difference between these two values.

The simple Brighton cycle consists of four processes:

Isentropic compression in the compressor.

Constant pressure heat addition in the combustion chamber.

Isentropic expansion in the turbine.

Constant pressure heat rejection to the surrounding environment.

Given data:

Inlet conditions:

Pressure at turbine inlet (P1) = 1 MPa

Temperature at turbine inlet (T1) = 1000 K

Exit conditions:

Pressure at turbine exit (P2) = 125 kPa

Temperature at turbine exit (T2) = 600 K

Heat expelled to the surrounding environment (Q_out) = 7922 kJ/s

Mass flow rate of air (m_dot) = 2.5 kg/s

First, let's calculate the specific enthalpy at state 1 (h1) using the air properties at the given temperature and pressure. You can refer to the air tables for this purpose.

Next, we need to calculate the specific enthalpy at state 2 (h2). We can use the temperature and pressure at state 2 and the air properties tables to determine h2.

Now, we can calculate the work done by the turbine (W_turbine) using the equation:

W_turbine = m_dot * (h1 - h2)

Since the compressor is assumed to be an isentropic process, the work done by the compressor (W_compressor) can be determined using the isentropic efficiency of the compressor (η_compressor) and the enthalpy difference between states 1 and 2:

W_compressor = (h2s - h1) / η_compressor

Where h2s is the specific enthalpy at state 2s, which can be determined using the temperature and pressure at state 2 and the air properties tables.

Finally, the net power produced (P_net) is given by:

P_net = W_turbine - W_compressor

Calculate the values using the above steps, and you will find the net power produced by the gas turbine power station.

2. A 100-MVA 11.5-kV 0.8-PF-lagging 50-Hz two-pole Y-connected synchronous generator has a per-unit synchronous reactance of 0.8 and a per-unit armature resistance of 0.012.
(a) What are its synchronous reactance and armature resistance in ohms?
(b) What is the magnitude of the intemal generated voltage E, at the rated conditions? What is its torque angle at these conditions?
(c) Ignoring losses, in this generator, what torque must be applied to its shaft by the prime mover at full load?

Answers

(a) To find the synchronous reactance and armature resistance in ohms, we need to convert the per-unit values to their corresponding actual values.

Given:

Per-unit synchronous reactance = 0.8

Per-unit armature resistance = 0.012

Base values:

Apparent power (Sbase) = 100 MVA

Voltage (Vbase) = 11.5 kV

To calculate the synchronous reactance in ohms:

Synchronous reactance (Xs) = Per-unit synchronous reactance * Xbase

Xbase = Vbase^2 / Sbase

Xs = 0.8 * (11.5 kV)^2 / 100 MVA

To calculate the armature resistance in ohms:

Armature resistance (Ra) = Per-unit armature resistance * Rbase

Rbase = Vbase^2 / Sbase

Ra = 0.012 * (11.5 kV)^2 / 100 MVA

(b) The magnitude of the internal generated voltage E at the rated conditions can be determined using the formula:

E = Vbase - (Ra + jXs) * I

where I is the rated current of the generator.

To find the torque angle at the rated conditions, we can use the power-angle equation:

tan(delta) = Xs / Ra

where delta is the torque angle.

(c) To determine the torque that must be applied to the generator shaft by the prime mover at full load, we can use the formula:

Torque = (Pout / (2 * pi * f)) / ((1 - s) * Ef)

where Pout is the output power at full load, f is the frequency, s is the slip, and Ef is the field voltage.

It's important to note that the slip (s) in a synchronous generator is zero because the rotor speed is synchronous with the stator frequency. Therefore, the torque required at full load would be zero since there is no slip-induced torque.

By calculating the above parameters, you can obtain the synchronous reactance and armature resistance in ohms, determine the magnitude of the internal generated voltage and torque angle at rated conditions, and understand that no additional torque is required at full load for a synchronous generator.

What is the typical maximum current that can be measured by a digital VOM?

Answers

Therefore, it's essential to select a digital VOM with a current measurement range appropriate for the intended application and to follow the manufacturer's instructions carefully when making current measurements.

The maximum current that can be measured by a digital VOM (Volt-Ohm-Meter) depends on the particular model of the device, as well as the type of current being measured.

Generally speaking, most digital VOMs have a current measuring range of a few milliamps (mA) to several amps (A).

For low current measurements, such as those in the milliamp range, digital VOMs typically have a maximum current measurement range of around 10 mA to 20 mA.

This range is suitable for measuring small currents in low-power electronic devices such as sensors, transducers, and other small components.

For higher current measurements, such as those in the ampere range, digital VOMs typically have a maximum current measurement range of around 10 A to 20 A.

This range is suitable for measuring the current drawn by larger electronic components such as motors, heaters, and other high-power devices.

However, it's important to note that attempting to measure currents beyond the range of the digital VOM can result in damage to the device or personal injury.

Assume all heat transfer occurs at a boundary temperature of 100°C. (b) Show the three processes on T-s diagram relative to the vapor dome and the appropriate lines of constant pressure for the four states. Label states and identify process directions with arrows.

Answers

Entropy generation for process 1 to 2: ΔSgen1-2 = 0 kJ/K, Entropy generation for process 3 to 4: ΔSgen3-4 = Q / T_boundary.

To calculate the entropy generation for each process, we need to determine the entropy change for each process and account for any entropy generation.

(a) Entropy generation for each process:

Process 1 to 2: Constant pressure process

Given:

Pressure at state 1 (P1) = 20 bar

Temperature at state 1 (T1) = 40°C = 313.15 K

Volume at state 2 (V2) = 0.42174 m³

First, we need to calculate the specific entropy change for this process using the ideal gas equation:

Δs1-2 = Cp * ln(T2/T1) - R * ln(V2/V1)

where Cp is the specific heat capacity at constant pressure and R is the specific gas constant.

Next, we need to calculate the entropy generation for this process. Since it is a constant pressure process, the entropy generation is zero.

Entropy generation for process 1 to 2: ΔSgen1-2 = 0 kJ/K

Process 2 to 3: Constant volume process

This process is a phase change from saturated liquid to saturated vapor. During a phase change, the entropy change is given by:

ΔS2-3 = m * Δh / T

where m is the mass of the substance, Δh is the enthalpy of vaporization, and T is the temperature.

To calculate the entropy generation for this process, we need to consider any heat transfer occurring at the boundary temperature of 100°C. The entropy generation can be calculated as:

ΔSgen2-3 = Q / T_boundary

where Q is the heat transfer and T_boundary is the boundary temperature.

Entropy generation for process 2 to 3: ΔSgen2-3 = Q / T_boundary

Process 3 to 4: Constant temperature polytropic process

This process is a polytropic process, and the entropy change can be calculated using the equation:

Δs3-4 = Cp * ln(T4/T3) - R * ln(P4/P3)

Entropy generation for this process can be calculated as:

ΔSgen3-4 = Q / T_boundary

where Q is the heat transfer and T_boundary is the boundary temperature.

Entropy generation for process 3 to 4: ΔSgen3-4 = Q / T_boundary

(b) The T-s diagram with the three processes, vapor dome, and lines of constant pressure can be sketched to visualize the states and process directions. Unfortunately, as a text-based AI model, I cannot provide a visual diagram. However, I recommend plotting the T-s diagram with the given information to accurately represent the processes and states.

First, we will calculate the magnetic field intensity at the center of the coil using the given formula:H = NI / (2r)where,N = Number of turns

I = Current flowing through the coil

r = radius of the coil (mean circumference / 2 * π)H = 500 * (24 / 20) / (2 * 0.79577) = 298.49 A/m

Now, the magnetizing force can be calculated as,F = H * l

where,l = length of the magnetic pathF = 298.49 * (50 / 100) = 149.25 AT/m(c) Calculation of total flux in the iron:Total flux (Φ) in the iron is given as,Φ = B * A where

,B = magnetic field intensityA = area of the cross-section of the ironTherefore, we need to calculate the magnetic field intensity inside the iron first.Using the given parameters, we can calculate the magnetic field inside the iron as,B = μr * μ0 * H

where,μr = Relative permeability of iron = 800μ0 = Permeability of free space = 4 * π * 10^-7T * m/AH = Magnetic field intensity = 298.49 A/mPutting all the values in the formula,B = 800 * 4 * π * 10^-7 * 298.49 = 0.7539 TTherefore,Φ = 0.7539 * 4 * 10^-4 = 3.0156 * 10^-4 Wb(d) Calculation of reluctance of the ring:The reluctance (R) of the iron ring is given as,R = l / (μr * μ0 * A)

where,l = length of the magnetic pathμr = Relative permeability of ironμ0 = Permeability of free spaceA = area of the cross-section of the ironPutting the values in the formula,R = (50 / 100) / (800 * 4 * π * 10^-7 * 4 * 10^-4) = 4.98 * 10^3 AT/WbAnswer:MMF of the coil = 600 A-T

Magnetizing force = 149.25 AT/m

Total flux in the iron = 3.0156 * \(10^{-4\) Wb

Reluctance of the ring = 4.98 * \(10^3\)AT/Wb

A circuit has a 12v power supply and a 1k ohm resistor. what is the current?

Answers

The current is I=12/1000, which simplifies to 0.012 amps or 12 milliamps.

Plugging these values into the equation, we get I=12/1000, which simplifies to 0.012 amps or 12 milliamps. It's important to note that the current in a circuit is dependent on the voltage and resistance in the circuit. If either of these values were to change, the current would also change accordingly. Additionally, it's important to ensure that the components in the circuit can handle the amount of current that is flowing through them to prevent damage or overheating.

Current in electric circuits refers to the flow of electric charge. It is the rate at which electric charges, typically electrons, move through a conductor. Current is measured in amperes (A) and is represented by the symbol "I". In a closed circuit, where there is a complete path for the electric charges to flow, a voltage difference (potential difference) is applied across the circuit.
