Answer:

- The mass flow rate of air is 4.59 kg/s

- Area of the exit turbine is 0.066 m²

Explanation:

 Given the data in the question;

Using air as an ideal gas.

Turbine;

state 1: p₁ = 8 bar, T₁ = 960 K

state 2: p₂ = 1 bar, T₂ = 450 K

The inlet velocity is small compared to the exit velocity of 90 m/s

V₁ < V₂ = 90 m/s

Power of turbine W' = 2500 kW

Now, lets assume Q = 0 and ΔPE = 0

we know that; R = 0.2870 kJ/kg-K

Also. \(C_p\) at 700K = 1.075 kJ/kg-K

Now, using ideal gas law;

STATE1

v₁ = RT₁/p₁

so we substitute

v₁ = [(0.2870 kJ/kg-K)(960 K)/(8 bars )]|\(\frac{bar}{10^5N/m^2}\)||\(\frac{1000N.m}{kJ}\)| =  0.344 m³/kg

STATE2

v₂ = RT₂/p₁

we substitute

v₂ = [(0.2870 kJ/kg-K)(450 K)/(1 bars )]|\(\frac{bar}{10^5N/m^2}\)||\(\frac{1000N.m}{kJ}\)| =  1.2915 m³/kg

Now, from energy balance steady state;

0 = Q" - W" + \(m"_i\)( \(h_i\) + \(\frac{V_i^2}{2}\) + \(gz_i\)) - \(m"_B\)( \(h_B\) + \(\frac{V_B^2}{2}\) + \(gz_B\))

since we initially assume Q = 0 and ΔPE = 0

hence;

0 = \(-\frac{W"}{m"}\) + h₁ + \(\frac{V_1^2}{2}\) -  h₂ + \(\frac{V_2^2}{2}\)

\(\frac{W"}{m"}\) = h₁ + \(\frac{V_1^2}{2}\) -  h₂ + \(\frac{V_2^2}{2}\)

⇒  \(\frac{W"}{m"}\) = \(C_p\)(T₁ - T₂) + \(\frac{1}{2}\)( V₁² - V₂²)

we solve for m"

m" = W" / (\(C_p\)(T₁ - T₂) + \(\frac{1}{2}\)( V₁² - V₂²))

so we substitute;

m" = {[2500 kW] / [(1.075kJ/kg-K(960K - 450k) + \(\frac{1}{2}\)( (0)² - (90 m/s)²)) |kJ/1000N.m| |N/kg.m/s²|]} | kJ/s / kW|

m" = 4.59 kg/s

Therefore, the mass flow rate of air is 4.59 kg/s

From the mass body steady state;

0 = m"₁ - m"₂

so

m"₁ = m"₂ = 4.59 kg/s

now, the volumetric flow rate V"₂ will be;

V"₂ = m" × v₂

we  substitute

V"₂ =  4.59 kg/s × 1.2915 m³/kg = 5.93 m³/s

and

the volumetric flow rate V"₂ = A₂V₂

so;

Exit Area A = V"₂ / V₂

we substitute

A = (5.93 m³/s ) / (90 m/s)

A = 0.06589 ≈ 0.066 m²

Therefore, Area of the exit turbine is 0.066 m²

Answer:

The answer is "F".

The sequence of drilling, boring, and reaming produces a hole that is more accurate than just drilling and reaming due to a combination of processes that refine and enhance the precision of the hole. Each step in the sequence contributes to improving the hole's accuracy, roundness, and surface finish.

1) Drilling is the initial process, which creates a rough hole in the material. This step often leaves uneven surfaces and an inaccurate hole diameter due to the drill bit's inherent limitations, such as deflection and wear.

2) Boring is the next step, which enlarges the hole to a more precise diameter using a single-point cutting tool. The boring process ensures a smoother, rounder, and more concentric hole compared to the initial drilled hole. Boring also allows for fine adjustments to the hole size, resulting in a more accurate dimension.

3)Finally, reaming further refines the hole's accuracy, roundness, and surface finish. The reamer, a multi-fluted cutting tool, removes a small amount of material from the hole's walls, correcting any remaining irregularities from the previous steps. Reaming also helps achieve tighter tolerances and better surface finish compared to just drilling and boring.

4)In conclusion, the sequence of drilling, boring, and reaming provides a more accurate hole due to the combined benefits of each process. Boring and reaming help eliminate inaccuracies and imperfections caused by the drilling process, resulting in a precise, round, and smooth hole that meets tighter tolerances and requirements.

A caisson is a watertight enclosure that can be pumped dry so that construction activities, such as the construction of piers can take place. A caisson is a watertight structure or chamber, usually made of wood, metal, or concrete, that is sunk to the bed of a river, lake, or ocean to provide a foundation or support for a bridge, building, or other structure.

A caisson is constructed onshore and then floated to the location where it is to be sunk into the water. Once in place, water is pumped out of the caisson, and construction workers enter the dry chamber to begin work on the foundation or support structure. The use of caissons has been an important development in the construction of bridges and other structures in areas with deep water or unstable soils.

A foundation called a caisson is used in construction on soft or deep water. It involves filling a series of large, watertight cylinders with concrete and sinking them into the ground. The base serves as a solid foundation for any subsequent structures. The construction of large structures like bridges, docks, and caissons is common.

Perfect Elastic Plastic in steel design is simply a method whereby the structural members are selected using the criteria of the overall ultimate capacity of the system. However, when safety is considered, the applied loads are usually increased by factors of safety as prescribed in the relevant steel design codes. Therefore, this model of design is just based on the yield capacity of the steel.

These transversal loads will result in a base shear V and a tension force M that both induce normal stress and shear stress, respectively.

It can seem like to use the term "a brief duration" in addition to referring to physical motion because the word minute appears to have Latin roots that signify movement, change, or alteration.

The orbital motion of water particles due to surface waves stops at a depth of "one-half the wavelength" (Option C).

Deep water waves (depth, D >λ /2) and shallow water waves (D < λ /20) both exhibit particle orbital motion. However, while deep water waves have a circular orbit, shallow water waves have an elliptical orbit with the primary axis in the horizontal plane [2, 3, 4, 5].

Instead, the water particles travel in circular orbits with a radius equal to wave height. This orbital motion arises because water waves include both longitudinally (side to side) and transverse (up and down) components, resulting in a circular motion.

The fat and protein contents of corn flour in dried basis are 1.213% and 6.549%, respectively. The fat and protein contents of wheat flour in dried basis are 2.041% and 14.655%, respectively.

Explanation: To convert the fat and protein contents of flour from wet basis to dry basis, we need to assume a certain moisture content to calculate the amount of dry matter in the flour. In this case, we will assume a moisture content of 0%, which means that we are calculating the fat and protein contents on a completely dry basis.

To calculate the fat and protein contents in dried basis, we can use the following formulas:

Fat (dried basis) = Fat (wet basis) / (1 - moisture content)

Protein (dried basis) = Protein (wet basis) / (1 - moisture content)

Using these formulas and the given values, we can calculate the fat and protein contents of corn flour and wheat flour in dried basis as follows:

For corn flour:

Fat (dried basis) = 1.2% / (1 - 0.12) = 1.213%

Protein (dried basis) = 6.5% / (1 - 0.12) = 6.549%

For wheat flour:

Fat (dried basis) = 2.0% / (1 - 0.14) = 2.041%

Protein (dried basis) = 14.0% / (1 - 0.14) = 14.655%

Hollowing out a uniform-diameter shaft increases its critical speed. The ratio of the critical speeds of a solid shaft of diameter d to a hollow shaft of inner diameter d/2 and outer diameter d is approximately 0.83.

When the diameter of a solid shaft is reduced by hollowing it out, the mass of the shaft decreases, and as a result, the critical speed increases. The reduction in mass means that the shaft is less likely to vibrate uncontrollably at high speeds.

The critical speed of a solid shaft of diameter d can be calculated using the formula: N = \((k * (E / rho)) ^ 0.5 * (d / L) ^ 0.5\), where N is the critical speed, k is a constant that depends on the end support conditions, E is the modulus of elasticity, rho is the density of the material, d is the diameter of the shaft, and L is the length of the shaft.

For a hollow shaft of inner diameter d/2 and outer diameter d, the formula for the critical speed becomes:

N = \((k * (E / rho)) ^ 0.5 * ((d/2)^2 + (d/2)^2) / L) ^ 0.5\)

Simplifying the formula, we get:

N =\((k * (E / rho)) ^ 0.5 * (d / L) * 0.707\)

Therefore, the ratio of the critical speeds of a solid shaft of diameter d to a hollow shaft of inner diameter d/2 and outer diameter d can be expressed as:

N_solid / N_hollow = \(((k * (E / rho)) ^ 0.5 * (d / L) ^ 0.5) / ((k * (E / rho)) ^ 0.5 * (d / L) * 0.707) = (d / (2 * d / sqrt(2))) ^ 0.5 = 0.83\)

Explanation:

In a battery-operated power supply, different DC voltages are obtained by using a voltage regulator.

A voltage regulator is a circuit that converts a power supply's voltage to a constant, desired level. This is necessary because the voltage of a battery can vary as it is used. By using a voltage regulator, the supply can maintain a constant voltage even as the battery's voltage changes.

Another way to obtain different DC voltages from a battery-operated power supply is by using a transformer. A transformer is a device that can step-up or step-down voltages. By using a transformer, the supply can convert the battery's voltage to the desired level.

In summary, different DC voltages can be obtained from a battery-operated power supply by using a voltage regulator or a transformer. These devices allow the supply to maintain a constant voltage even as the battery's voltage changes.

Answer:

water released through the bottom of the reservoir in 24 hrs is 1992 ha-cm

Explanation:

Given the data in the question;

A = 200 hectare =  2 × 10⁶ m²

water evaporated Ve = 2 × 10⁶ m² × 3 × 10⁻² = 60000 m³ { in 24 hrs }

Water added by storm in 24hrs Vi = 3 × 24 × 3600 = 259200 m³

now let water released be Vr

ΔV = V_ini - V_final = 0

Vi - Ve - Vr = 0

Vr = Vi - Ve

Vr = 259200 m³ - 60000 m³

Vr = 199200 m³ = 19920000 m² - cm

Vr = 1992 ha-cm

Therefore, water released through the bottom of the reservoir in 24 hrs is 1992 ha-cm

In an experiment, the variable that is manipulated by the researcher is called the independent variable.

The independent variable is the factor or condition that the researcher deliberately changes or controls to observe its effect on the dependent variable. The independent variable is often denoted as "X" and is the presumed cause or predictor variable in the experiment. The researcher selects the values or levels of the independent variable and manipulates it systematically across different experimental conditions or groups.

For example, in a study investigating the effect of different fertilizer types on plant growth, the researcher may manipulate the independent variable, which is the type of fertilizer applied to the plants. The researcher may have different groups of plants, each receiving a different fertilizer type (e.g., Group A: Fertilizer X, Group B: Fertilizer Y, etc.). By manipulating the independent variable, the researcher can observe and measure how the different fertilizer types impact the dependent variable, which in this case would be the plant growth.

It is important to carefully control and manipulate the independent variable to ensure that any observed effects on the dependent variable can be attributed to the changes in the independent variable rather than other factors. This allows researchers to establish cause-and-effect relationships and draw valid conclusions from their experiments.

The size of the tag field is byte-addressable computer using direct mapping with 16-bit main memory addresses and 32 blocks of cache. If each block contains 8 bytes, determine the size of the tag field is 8 bits.

a 4 b. 8 c. 3 d. 2 e. 10.

The paragraph describes a scenario where we have a byte-addressable computer using direct mapping and we need to determine the size of the tag field given the number of blocks of cache, the block size and the size of the main memory addresses.

In this scenario, since we have 32 blocks of cache and each block contains 8 bytes, the total size of the cache is 32 * 8 = 256 bytes.

To determine the size of the tag field, we need to find the number of bits needed to uniquely identify each block in the main memory.

Since the main memory addresses are 16 bits, we can use log base 2 of the number of blocks to determine the number of bits needed for the index field, which is log2(32) = 5 bits.

The remaining bits will be used for the tag field.

Therefore, the size of the tag field is 16 - 5 - 3 = 8 bits (where 3 bits are used for the byte offset).

So the answer is (b) 8.

Pressure altitude is the vertical distance above the standard datum plane, whereas Density altitude is the height in the International Standard Atmosphere at which the air density is equal to the actual air density at the place of observation.

Pressure Altitude Pressure Altitude is a term used to describe the altitude of an aircraft above a given datum plane. It is measured by an altimeter that has been calibrated to read pressure rather than altitude. This is because pressure is directly proportional to the altitude, and so changes in pressure can be used to determine changes in altitude. Density Altitude Density Altitude is the altitude in the International Standard Atmosphere (ISA) at which the air density is equal to the actual air density at the place of observation.

The question is incomplete. Here is the complete question.

Two kg of a two phase liquid vapor mixture of carbon dioxide (CO₂) exists at -40°C in a 0.05m³ tank. Determine the quality of the mixture, if the values of specific volume for saturated liquid and saturated vapor CO₂ at -40°C are \(v_{f}\) = 0.896 x 10⁻³m³/kg and \(v_{g}=\) 3.824 x 10⁻²m³/kg, respectively.

Answer: x = 1

Explanation: In a phase change of a pure substance, at determined pressure and temperature, the substance exists in two different phases: saturated liquid and saturated vapor.

Quality (x) is the ratio of saturated vapor in the mixture and can be written as:

\(x=\frac{m_{vapor}}{m_{liquid}+m_{vapor}}\)

It has value between 0 and 1: x = 0 for saturated liquid and x = 1 for saturated vapor.

When related with volumes, quality is rearranged as:

\(x=\frac{v-v_{f}}{v_{g}-v_{f}}\)

Solving for x:

\(x=\frac{0.05-0.896.10^{-3}}{3.824.10^{-2}-0.896.10^{-3}}\)

\(x=\frac{0.049104}{0.037344}\)

x = 1.3

Quality of mixture of carbon dioxide is x = 1, which means it's for saturated vapor.
