a disadvantage shared by wave, solar and wind energy is that __________.

When a motor running at synch speed gets caught in a load, the torque increases while the speed and frequency decrease.

This is because the motor is no longer running at its synchronous speed, resulting in a decrease in frequency and speed while an increase in torque. What is synchronous speed? Synchronous speed is the speed at which a motor's rotating magnetic field moves. It is determined by the number of stator poles and the frequency of the supply current. A synchronous motor's rotor rotates at the same speed as its stator's rotating magnetic field at synchronous speed. What is torque? A torque is a rotational force that is applied to an object. It is the force that causes an object to rotate around a pivot point or axis. Torque is usually measured in units of Newton meters (N-m) or pound-feet (lb-ft). What is the frequency? In electrical engineering, frequency refers to the number of cycles per second of an alternating current (AC) signal. The frequency of an AC signal is measured in hertz (Hz), which is equivalent to cycles per second.

Answer:

Explanation:

If the museum is running short of funds, and you decide to increase revenue. An increase or decrease in the price of admission into the museum depends on the following:

1. If demand for admission into the museum is elastic there are two possible outcomes

a. An increase in the price of admission leads to a decrease in the quantity demand of admission into the museum

b. A decrease in price of admission into the museum leads to an increase in the quantity demand of admission into the museum.

This follows the law of demand which states that "the higher the price, the lower the quantity demanded and the lower the price, the higher the quantity demanded".

2. If the demand for admission into the museum is inelastic, then an increase in price will lead to an increase in revenue of the museum.

Therefore, before the curator increase the price of admission into the museum, he should first determine the price elasticity of demand of the museum.

Answer:

a) specific work output of the actual turbine is 73.14 Btu/lbm

b) the amount of specific entropy generation during the irreversible process is 0.050416 Btu/lbm°R

c) Isentropic efficiency of the turbine is  70.76%

Explanation:

Given the data in the question;

For an adiabatic turbine; heat loss Q = 0

For Initial State;

p₁ = 120 psia

T₁ = 500°F = 959.67°R

from table; { Gas Properties of Air }

At T₁ = 959.67°R

\(s_1^0\) = 0.74102 Btu/lbm°R

\(h_1\) = 230.98 Btu/lbm

For Finial state;

p₂ = 15 psia

T₂ = 200°F = 659.67°R

\(s^0_{2a\) = 0.64889 Btu/lbm°R

\(h_{2a\) = 157.84 Btu/lbm

we know that R for air is 0.06855 Btu/lbm.R

a)

The specific work output of the actual turbine Wₐ is;

W\(_a\) = \(h_1\)  - \(h_{2a\)

we substitute

W\(_a\) = 230.98 - 157.84

W\(_a\) = 73.14 Btu/lbm

Therefore, specific work output of the actual turbine is 73.14 Btu/lbm

b)

amount of specific entropy generation during the irreversible process.

To determine the entropy generation \(S_{gen\);

\(S_{gen\) = ΔS = \(s_{2a\) - \(s_1\) =  \(s^0_{2a\)  - \(s_1^0\) - R ln(\(\frac{p_2}{p_1}\))

we substitute in our values

\(S_{gen\) = 0.64889 - 0.74102 - 0.06855 ln(\(\frac{15}{120}\))

\(S_{gen\) = 0.64889 - 0.74102 + 0.1425457

\(S_{gen\) = 0.050416 Btu/lbm°R

Therefore, the amount of specific entropy generation during the irreversible process is 0.050416 Btu/lbm°R

c)

Isentropic efficiency of turbine η\(_{is\)

η\(_{is\) = {actual work output] / [ ideal work output ] = (\(h_1\)  - \(h_{2a\) ) / ( \(h_1\)  - \(h_{2s\) )

Now, for an ideal turbine;

ΔS = 0 = \(s_{2s\) - \(s_1\)

so, \(s_{2s\) - s₁  = \(s^0_{2s\) - \(s_1^0\) - R ln(\(\frac{p_2}{p_1}\))

0 =  \(s^0_{2s\) - \(s_1^0\) - R ln(\(\frac{p_2}{p_1}\))

\(s^0_{2s\)  = \(s_1^0\) + R ln(\(\frac{p_2}{p_1}\))

we substitute

\(s^0_{2s\)  = 0.74102 + 0.06855 ln(\(\frac{15}{120}\))

\(s^0_{2s\)  = 0.74102 - 0.1425457

\(s^0_{2s\)  = 0.59847 Btu/lbm°R

Now, from table; { Gas Properties of Air }

At \(s^0_{2s\)  = 0.59847 Btu/lbm°R; \(h_{2s\)  = 127.614 Btu/lbm

η\(_{is\)  = [( \(h_1\)  - \(h_{2a\) ) / ( \(h_1\)  - \(h_{2s\)  )] × 100%

we substitute

η\(_{is\)  = [( 230.98 - 157.84 ) / ( 230.98 - 127.614 )] × 100%

η\(_{is\)  = [ 73.14 / 103.366] × 100%

η\(_{is\)  = 0.70758 × 100%

η\(_{is\)  = 70.76%

Therefore, Isentropic efficiency of the turbine is  70.76%

1. We can see here that three phase refers to a type of electrical power transmission that uses three alternating current (AC) waveforms that are 120 degrees out of phase with each other. This is different from single-phase power transmission, which uses only one AC waveform.

Voltage, also known as electric potential difference, is a measure of the electrical potential energy per unit of charge in an electrical circuit. It is defined as the amount of work required to move a unit of electric charge between two points in a circuit, typically measured in volts (V).

Three-phase power is needed because it allows for more power to be transmitted over a given amount of wire or cable. With three-phase power, the power is delivered in a more consistent manner, which means that there is less voltage drop over long distances.

2. In order for a three-phase system to be balanced, the three phases must have the same amplitude and be 120 degrees out of phase with each other. The voltage equation of a balanced three-phase voltage source is given by:

Vph = Vline / √3

Note that  the magnitudes of the two forces are F1 = √6 N and F2 = 2 N.

Let F1 and F2 be the magnitudes of the two forces. If they act at right angles, their resultant R is given by:

R = √(F1^2 + F2^2)

If they act at 60 degrees, their resultant R' is given by:

R' = √(F1^2 + F2^2 + 2F1F2cos60°) = √(F1^2 + F2^2 + F1F2)

We can set up a system of equations to solve for F1 and F2:

√(F1^2 + F2^2) = √10 ...(1)

√(F1^2 + F2^2 + F1F2) = √13 ...(2)

Squaring both sides of equation (1), we get:

F1^2 + F2^2 = 10

Squaring both sides of equation (2), we get:

F1^2 + F2^2 + F1F2 = 13

Substituting F1^2 + F2^2 = 10 from equation (1), we get:

10 + F1F2 = 13

F1F2 = 3

Now, we can solve for F1 and F2 using the equations:

F1^2 + F2^2 = 10

F1F2 = 3

Multiplying the second equation by 4, we get:

4F1F2 = 12

Substituting F1F2 = 3, we get:

12 = 3(F1^2 + F2^2)

Simplifying, we get:

F1^2 + F2^2 = 4

Using this equation and F1F2 = 3, we can solve for F1 and F2:

F1^2 + F2^2 = 4

F1F2 = 3

Multiplying the first equation by F1F2, we get:

F1^2F2 + F1F2^2 = 12

Substituting F1F2 = 3, we get:

F1^2 + 3F2^2 = 12

Substituting F1^2 = 4 - F2^2 from the first equation, we get:

4 - F2^2 + 3F2^2 = 12

Simplifying, we get:

2F2^2 = 8

F2^2 = 4

F2 = 2

Substituting F2 = 2 in F1^2 + F2^2 = 10, we get:

F1^2 + 4 = 10

F1^2 = 6

F1 = √6

Alternative C has the highest Incremental Benefit/Cost Ratio, followed by Alternative B, making them more preferable than Alternative A.

To compare the three alternatives (A, B, and C) using the Incremental Benefit/Cost Ratio method at a discount rate of 4% per year, we need to calculate the present value of costs, present value of benefits, and incremental benefit/cost ratio for each alternative.

Step 1: Calculate the present value of costs and benefits for each alternative.

For Alternative A:

- Construction Cost: $250,000

- Benefits per year: $320,000

- Service Life: 7 years

Using the formula for present value, we can calculate the present value of costs and benefits for Alternative A:

Present Value of Costs (PV A) = Construction Cost / (1 + discount rate)^service life = $250,000 / (1 + 0.04)^7 ≈ $186,065.69

Present Value of Benefits (PV A) = Benefits per year * (1 - (1 + discount rate)^-service life) / discount rate = $320,000 * (1 - (1 + 0.04)^-7) / 0.04 ≈ $1,883,076.14

For Alternative B and C, follow the same steps to calculate their respective present value of costs and benefits:

Alternative B:

- Construction Cost: $400,000

- Benefits per year: $370,000

- Service Life: 15 years

PV B (Cost) ≈ $267,507.55

PV B (Benefits) ≈ $3,048,852.53

Alternative C:

- Construction Cost: $700,000

- Benefits per year: $380,000

- Service Life: 25 years

PV C (Cost) ≈ $395,661.79

PV C (Benefits) ≈ $6,750,228.83

Step 2: Calculate the incremental benefit and incremental cost between each alternative and the previous one.

Incremental Benefit (IB) = Present Value of Benefits (Current Alternative) - Present Value of Benefits (Previous Alternative)

Incremental Cost (IC) = Present Value of Costs (Current Alternative) - Present Value of Costs (Previous Alternative)

IB_AB = PV B (Benefits) - PV A (Benefits) ≈ $3,048,852.53 - $1,883,076.14 ≈ $1,165,776.39

IC_AB = PV B (Cost) - PV A (Cost) ≈ $267,507.55 - $186,065.69 ≈ $81,441.86

IB_BC = PV C (Benefits) - PV B (Benefits) ≈ $6,750,228.83 - $3,048,852.53 ≈ $3,701,376.30

IC_BC = PV C (Cost) - PV B (Cost) ≈ $395,661.79 - $267,507.55 ≈ $128,154.24

Step 3: Calculate the Incremental Benefit/Cost Ratio (IB/IC) for each alternative.

IB/IC ratio = Incremental Benefit / Incremental Cost

IB/IC_AB = $1,165,776.39 / $81,441.86 ≈ 14.31

IB/IC_BC = $3,701,376.30 / $128,154.24 ≈ 28.91

Step 4: Compare the Incremental Benefit/Cost Ratios.

Since IB/IC_AB is less than IB/IC_BC, we can conclude that Alternative B is preferred over Alternative A, and Alternative C is preferred over Alternative B.

In summary, based on the Incremental Benefit/Cost Ratio method at a 4% discount rate per year, the

ranking of the alternatives from most preferred to least preferred is:

If the numbers are considered "signed", then the top diagram will generate an "overflow" based on the difference between the carry C4 and the output O4.

One type of infrastructure support that is not currently under consideration to keep sewer systems in cities from experiencing overflows is the implementation of green infrastructure. Green infrastructure refers to the use of natural systems such as permeable pavement, rain gardens, and green roofs to manage stormwater runoff. These natural systems help to absorb and filter rainwater, reducing the amount of water that enters the sewer system.

However, despite their effectiveness in preventing overflows, green infrastructure is often not considered due to various reasons.

One reason is the lack of awareness and understanding of the benefits of green infrastructure among city planners and policymakers. Many cities still rely heavily on traditional gray infrastructure, such as large pipes and storage tanks, to manage stormwater. This outdated approach may be seen as more reliable and familiar, even though it can be costly and less environmentally friendly.

Another reason is the perception that green infrastructure is not suitable for urban environments. There is a misconception that these natural systems require a significant amount of space, which may be limited in densely populated cities.

However, there are innovative approaches to implementing green infrastructure in urban areas, such as using green roofs on buildings or retrofitting existing infrastructure.

Additionally, the upfront costs of implementing green infrastructure can be a deterrent for some cities. While green infrastructure may be more cost-effective in the long run due to lower maintenance and operation costs, the initial investment required can be higher compared to traditional gray infrastructure.

This financial barrier may prevent cities from considering green infrastructure as an option.

Green infrastructure is not currently under consideration as a type of infrastructure support to prevent sewer system overflows in cities. This can be attributed to factors such as lack of awareness and understanding, misconceptions about its suitability for urban environments, and upfront costs.

However, promoting the benefits and exploring innovative approaches can help overcome these barriers and encourage the adoption of green infrastructure to mitigate overflows in sewer systems.

Answer:

To calculate the steady state flux of atomic hydrogen through a steel vessel, we need to use Fick's first law, which states that the flux (J) is equal to the diffusivity (D) multiplied by the concentration gradient (dC/dx).

First, we need to calculate the concentration gradient by dividing the difference in hydrogen concentration between the inside and outside surfaces by the wall thickness of the vessel. The inside surface is kept saturated with hydrogen at a concentration of 4.5 moles/m3, and the outside surface is exposed to the atmosphere, which has a hydrogen concentration of 0 moles/m3. Therefore, the concentration gradient is (4.5 - 0) moles/m3 / (4 mm) = 1.125 moles/m3 mm.

Next, we need to substitute this value into Fick's first law along with the diffusivity of hydrogen in steel, which is given as 0.1 mm2/s. This gives us the steady state flux as J = (-0.1 mm2/s) * (1.125 moles/m3 mm) = -0.01125 moles/s mm2.

Finally, we need to convert the units of the flux from moles/s mm2 to moles/s m2. To do this, we can multiply the flux by 1,000 to convert the units of millimeters to meters, giving us a final steady state flux of -0.01125 moles/s mm2 * 1,000 = -1.125 moles/s m2.

IF THE VESSEL CONTAINS 20 MOLES OF HYDROGEN, CALCULATE THE TIME TAKEN TO DISSIPATE ALL OF THE HYDROGEN OF THAT THE VESSEL HAS A SURFACE AREA OF 3 M2.

To solve this problem, we need to first calculate the flux of atomic hydrogen through the vessel using Fick's first law:

J = -D(dC/dx)

where J is the flux, D is the diffusivity of hydrogen in steel, and dC/dx is the concentration gradient.

Given that the diffusivity of hydrogen in steel is 0.1 mm2/s, the inside concentration is 4.5 moles/m3, and the outside concentration is 0, the concentration gradient is 4.5 moles/m3.

Plugging these values into the equation above, we get:

J = -0.1 mm2/s * 4.5 moles/m3 = -0.45 moles/s-m2

Next, we need to calculate the time it takes to dissipate all 20 moles of hydrogen from the vessel. We can do this by dividing the total number of moles of hydrogen by the flux:

t = 20 moles / (-0.45 moles/s-m2) = 44.44 s

So it would take approximately 44.44 seconds to dissipate all of the hydrogen from the vessel.

Explanation:

The time taken is 44.44 seconds to dissipate all of the hydrogens from the vessel.

To solve this problem, we need to first calculate the flux of atomic hydrogen through the vessel using Fick's first law:

J = -D(dC/dx)

where J is the flux, D is the diffusivity of hydrogen in steel, and dC/dx is the concentration gradient.

Given that the diffusivity of hydrogen in steel is 0.1 mm²/s, the inside concentration is 4.5 moles/m³ and the outside concentration is 0, the concentration gradient is 4.5 moles/m³.

Plugging these values into the equation above, we get:

J = -0.1 mm²/s * 4.5 moles/m³ = -0.45 moles/s-m²

Next, we need to calculate the time it takes to dissipate all 20 moles of hydrogen from the vessel. We can do this by dividing the total number of moles of hydrogen by the flux:

t = 20 moles / (-0.45 moles/s-m2) = 44.44 s

So it would take approximately 44.44 seconds to dissipate all of the hydrogen from the vessel.
