Answer:

Use a non digital multimeter.

Explanation:

If a digital multimeter displays "000" when reading amperage, the technician should adjust the multimeter to a higher amperage range.

This is because "000" typically indicates that the current being measured is too low for the current range selected on the multimeter.

By switching to a higher amperage range, the technician can get a more accurate reading and ensure that the multimeter is properly measuring the current in the circuit under test.

Explanation:

To obtain the magnitude and phase Bode plots of the transfer function using AC simulation, you can use simulation software such as SPICE (Simulation Program with Integrated Circuit Emphasis). Input the circuit schematics with the calculated component values into the software.

Measure the 3-dB frequencies and passband gains from the Bode plots. The 3-dB frequencies are the frequencies where the magnitude of the transfer function is reduced by 3 dB (half-power point). The passband gain is the gain within the desired frequency range.

Measure the magnitude and phase of the transfer function at 4 kHz and 6 kHz by reading the values from the Bode plots at these frequencies.

Apply the input vi(t) to the circuit by providing a voltage source or signal generator with the desired waveform and frequency. Measure the response of the circuit using simulation software.

Remember to properly label the plots and provide all the requested information.

The bonding means required in 501.30(a) are generally required to be installed from the hazardous (classified) location to the point of grounding of a separately derived system that is the source of the circuit.

Bonding means in hazardous locations, as specified in 501.30(a), serve the purpose of establishing an effective electrical bond between the hazardous location and the grounding system of a separately derived system that supplies power to the location. This bonding is necessary to prevent the accumulation of static electricity or the development of potential differences that could lead to the ignition of flammable substances present in the hazardous area.

In hazardous locations, there is a higher risk of the release of flammable gases, vapors, or dust particles, which can create a hazardous atmosphere. The bonding means, typically in the form of conductive paths or conductive equipment, ensure that any potential difference or electrical charge is safely discharged, reducing the risk of sparks or arcs that could trigger an explosion.

By analyzing the behavior of the order parameter as we approach the tricritical point along the r-axis with s = 0, we were able to determine the critical exponents for this model.

To approach the tricritical point along the r-axis, we set s = 0 and let r ≈ r1t. This means we are looking at a specific region of the phase diagram for this model. To determine the critical exponents for the tricritical point, we need to analyze the behavior of the order parameter as we approach the critical point.

Using scaling arguments, we can derive the following relationships between the critical exponents:
β = (δ - 1) / (α - 1)
γ = (α + 2β - 1) / (α - 1)

Since δ = s and we are approaching the tricritical point along the r-axis with s = 0, we have δ = 0. We are given that r ≈ r1t, which implies that we are close to the critical point and can assume that α is close to 1.

Substituting these values into the scaling relationships, we get β = -1/4 and γ = 1/2. Solving for α using the first relationship, we get α = 1/2.

Therefore, the critical exponents pertaining to the tricritical point in this model are α = 1/2, β = -1/4, γ = 1/2, and δ = 0.

Answer:

Plain carbon steel has no or trace external elements while alloy steel has high amount of other elements.

Explanation:

Plain carbon steel has no or trace amount of other elements while alloy steel has high amount of other elements in their composition.

The presence of other elements in alloy steel improvise several physical properties of the steel while plain carbon steel has the basic properties.

a. Compressor work: 2665 kJ/s

b. Turbine work: 3960 kJ/s

c. Heat supplied: 4220 kJ/s

d. Thermal efficiency: 30.6%

Assuming a simple Brayton cycle for the gas turbine, and given:

Pressure ratio (rp) = 6

Inlet pressure (P1) = 1.013 bar

Inlet temperature (T1) = 288 K

Turbine inlet temperature (T3) = 700 °C = 973 K

Mass flow rate (m) = 10 kg/s

We'll use air as an ideal gas with constant specific heat ratios:

Specific heat at constant pressure (cp) = 1.005 kJ/(kg·K)

Specific heat at constant volume (cv) = 0.718 kJ/(kg·K)

Isentropic index (γ) = cp / cv = 1.4

a. Compressor work (Wc):

The temperature at the compressor exit (T2) can be calculated using the isentropic temperature relation:

T2 / T1 = (P2 / P1)^((γ - 1) / γ)

T2 = T1 * (rp)^((γ - 1) / γ) = 288 * (6)^((1.4 - 1) / 1.4) ≈ 553 K

Wc = m * cp * (T2 - T1) = 10 * 1.005 * (553 - 288) ≈ 2665 kJ/s

b. Turbine work (Wt):

The temperature at the turbine exit (T4) can be calculated using the isentropic temperature relation:

T4 ≈ 579 K

Wt = 3960 kJ/s

c. Heat supplied (Q):

Q = m * cp * (T3 - T2) = 10 * 1.005 * (973 - 553) ≈ 4220 kJ/s

d. Thermal efficiency (η):

η = (Wt - Wc) / Q = (3960 - 2665) / 4220 ≈ 0.306 or 30.6%

In summary:

a. Compressor work: 2665 kJ/s

b. Turbine work: 3960 kJ/s

Answer:

The plumbing is designed to reduce the impact of pressure forces due to the height of skyscrapers. This is achieves by narrowing down the pipe down to the basement, using pipes with thicker walls down the basement, and allowing vents; to prevent clogging of the pipes.

Explanation:

Pressure increases with depth and density. In skyscrapers, a huge problem arises due to the very tall height of most skyscrapers. Also, sewage slug coming down has an increased density when compared to that of water, and these two factors can't be manipulated. The only option is to manipulate the pipe design. Pipes in skyscrapers are narrowed down with height, to reduce accumulation at the bottom basement before going to the sewage tank. Standard vents are provided along the pipes, to prevent clogging of the pipes, and pipes with thicker walls are used as you go down the basement of the skyscraper, to withstand the pressure of the sewage coming down the pipes.

The Dry Unit Weight of the soil is 17.5 kN/m3, the Void Ratio is 0.347, the Porosity is 0.384, and the Degree of Saturation is 86.7%.

B. The Dry Unit Weight of the soil can be calculated using the formula γd = γw(1-w), where γd is the dry unit weight, γw is the moist unit weight, and w is the moisture content.

In this case,  γd = γw(1-w)

γd = 19.6(1-0.143) = 17.5 kN/m3.

The Void Ratio is then calculated using the formula e = (w / (1-w)), where e is the void ratio and w is the moisture content. Plugging in the values from above,

e = (w / (1-w))

e = 0.143/(1-0.143) = 0.347.

The Porosity is then calculated using the formula n = e/[1 + (G•e)], where n is the porosity, e is the void ratio, and G is the specific gravity. In this case,

n = e/[1 + (G•e)]

n = 0.347/[1 + (2.75•0.347)] = 0.384.

Finally, the Degree of Saturation can be calculated using the formula S = w/(1 + (G•e)), where S is the degree of saturation and the other variables are the same as above. Thus,

S = w/(1 + (G•e))

S = 0.143/(1 + (2.75•0.347)) = 0.867 or 86.7%.

The investigations of Count Rumford and Sir Humphry Davy were among the first to shed doubts about the caloric theory of heat.

They conducted experiments that showed the relationship between mechanical work and heat, which contradicted the caloric theory that heat was a fluid substance. Later, the work of James Prescott Joule and others provided further evidence that heat was a form of energy, rather than a substance.

The caloric theory of heat was a scientific model that was popular in the 18th and early 19th centuries. It proposed that heat was not a form of energy, but rather a type of fluid called "caloric" that flowed from hotter objects to colder objects. The theory was developed to explain the nature of heat and how it was transferred between objects.

According to the caloric theory of heat, when an object was heated, it absorbed caloric, which caused its temperature to increase. When an object was cooled, it released caloric, which caused its temperature to decrease. The theory also proposed that heat was not a conserved quantity, meaning that it could be destroyed or created, in contrast to the modern understanding of thermodynamics, which holds that energy is always conserved.

The electricity cost of the refrigerator per month, running only one quarter of the time, is : option (a) $4.9.

The power consumed by the refrigerator, P = 320 W

Unit cost of electricity, C = $0.13/kWh

Let the time for which the refrigerator runs in a day = t.

The total time taken by the refrigerator for running in 30 days = 30t.

We know that,Energy consumed = power x time. Therefore,The energy consumed by the refrigerator in

30 days = P × 30t = 320 × 30t = 9600t Wh

The electricity cost for 1 kWh = $0.13

Therefore, the electricity cost for 9600t Wh = $0.13 × 9600t = 1248t cents

We know that, 100 cents = $1

Therefore, the electricity cost for 9600t Wh = 12.48t $For 24 hours, the refrigerator runs 1/4th of the time.So,

t = (1/4) × 24 = 6 hours = 0.25 days

Therefore, The energy consumed by the refrigerator in 30 days = 9600t Wh = 9600 × 0.25 Wh = 2400 Wh = 2.4 kWh

The electricity cost for 2.4 kWh = 2.4 × 0.13 = $0.312Therefore, the main answer is option (a) $4.9.
