reservoir is 727°C, then low temperature
reservoir will have to be maintained at °C

Answers

Answer 1

Answer:

reservoir is 727°C, then low temperature

Explanation:

Efficiency for any Heat engine = Work done by engine / Heat provided to the engine

Also, for a carnot engine derived formula for Carnot Engine

= 1- T2/T1

Where, T2 = sink reservoir temperature

and T1 = source reservoir temperature

727° C = 1000 K

So, 0.75 = 1-T2 / 1000

So, T2 = 1000*0.25 = 250 K = -23 Kelvin

the most commonly installed type of fire sprinkler systems are? pre-action systems dry-pipe systems wet-pipe systems deluge systems

Answers

The most commonly installed type of fire sprinkler system is the wet-pipe system. In a wet-pipe system, the pipes are filled with water and are pressurized so that when the heat of a fire activates the sprinkler head, water is released onto the fire.

Pre-action systems use a separate water line to fill the pipes with water and need to be triggered by another type of detector such as smoke or heat, while dry-pipe systems have pressurized air or nitrogen in the pipes and the water is released when the heat of a fire activates the sprinkler head. Deluge systems are used when large amounts of water need to be released quickly, such as when a large area needs to be flooded quickly.

In order to install a wet-pipe system, the pipes must be connected to a water source and the sprinkler heads must be placed at the correct height in the room. Once the system is installed, it must be tested regularly to make sure that it is functioning properly. It is also important to remember that water damage can be caused by a malfunctioning system, so it is important to regularly check and maintain the system.

What should the technician always check when replacing a transformer in an electric heating system to prevent the new transformer from failing like the old one

Answers

When replacing a transformer in an electric heating system, the technician should always check several things to prevent the new transformer from failing like the old one.

These things include the following:1. Power Supply: Check the power supply that feeds the transformer and verify that it's the right voltage. Make sure the transformer is being supplied with the correct voltage and frequency. Also, check for any loose wiring or connections that could cause voltage drops.

If the voltage is too high or too low, it can cause the transformer to fail.2. Load: Verify the electrical load that the transformer is serving and ensure that it is within the transformer's rated capacity. If the load is too high, it can cause the transformer to overheat and fail. If the load is too low, it can cause the transformer to burn out due to insufficient cooling.3. Grounding: Check the transformer's grounding connection to ensure it is connected correctly.

If the grounding is poor, it can cause voltage surges, which can damage the transformer.4. Protection: Check the transformer's protection circuitry to make sure it is working correctly. The protection circuitry is designed to protect the transformer from overloads, overcurrents, and short circuits.

If the protection circuitry is faulty, the transformer can fail.5. Environmental factors: Verify the environmental factors that may be affecting the transformer's operation. Things like temperature, humidity, and vibration can affect the transformer's operation. If the transformer is exposed to high temperatures or vibration, it can cause the winding insulation to break down, which can cause the transformer to fail.

Therefore, when replacing a transformer in an electric heating system, the technician should always check the power supply, load, grounding, protection circuitry, and environmental factors to ensure that the new transformer does not fail like the old one.

An integer is a whole number without any decimal points, which can be positive or negative. Integers larger than or equal to zero are referred to as non-negative integers.

We can use a loop to continuously read integers from the user up until a negative number is entered in order to create such a program. The maximum and average of the non-negative integers entered are then computed while disregarding the negative integer. The largest integer in the set serves as the maximum. As we read in the data, we may utilize a variable to keep track of the greatest number. The variable will have the highest value when the loop is finished. The average is calculated by dividing the total number of integers by the sum of all the integer. We increase the count and add each non-negative integer to the total. We divide the sum by the count at the conclusion of the loop.

The settlement analysis for a proposed structure indicates that the underlying clay layer will settle 7.5 cm in 3 years, and that ultimately the total settlement will be about 32 cm. However, this analysis is based on the clay layer being doubly drained. It is suspected that there may be no drainage at the bottom of the layer (i.e., clay has single drainage condition). Answer the following questions based on single drainage only, assuming cv = 1.5 x 10-4 cm 2 /s for both single and double drainage.

a. How will the total settlement change from the double to the single drainage case?
b. How long will it take for 7.5 cm of settlement to occur if there is only single

Answers

Answer:

A) For a double drainage system the time taken for total settlement will differ from that of a single drainage system, because in a double drainage case clay water escapes from both sides unlike in a single drainage case. hence water and air will be be expulsed faster for a double drainage making it attain  total settlement faster.

B) for only single = 12 years

Explanation:

Given data :

ultimate clay settlement = 32 cm

settlement of clay in 3 years = 7.5 cm

Cv ( coefficient of consolidation ) =  1.5 x 10^-4 cm^2 /s

A) For a double drainage system the time taken for total settlement will differ from that of a single drainage system, because in a double drainage case clay water escapes from both sides unlike in a single drainage case. hence water and air will be be expulsed faster for a double drainage making it attain  total settlement faster.

note : Total settlement is the same in both drainage system.

B) Determine how long it will take for 7.5 cm of settlement to occur if there is only single

applying the relation  below

Tv = Cv t / H^2

where Tv = time factor , d = thickness of layer , H = drainage path

Given that Tv and Cv are constant in both cases

t ∝ H^2   hence

\(\frac{t1}{t2} = \frac{H^21}{H^22}\)  ------ ( 1 )

t1 = time for single drainage for d meters , t2 = time for double drainage  for d meters

equation 1 can be rewritten as

t1/t2 = d^2 / (d/2)^2

∴ t1 = 4t2

given that t2 = 3 years ( value gotten from question )

t1 = 4 * 3 = 12 years

A river has an average rate of water flow of 59.6 M3/s. This river has three tributaries, tributary A, B and C, which account for 36%, 47% and 17% of water flow respectively. How much water is discharged in 30 minutes from tributary B?

Answers

Answer:

50421.6 m³

Explanation:

The river has an average rate of water flow of 59.6 m³/s.

Tributary B accounts for 47% of the rate of water flow. Therefore the rate of water flow through tributary B is:

Flow rate of water through tributary B = 47% of 59.6 m³/s = 0.47 * 59.6 m³/s = 28.012 m³/s

The volume of water that has been discharged through tributary B = Flow rate of water through tributary B * time taken

time = 30 minutes = 30 minutes * 60 seconds / minute = 1800 seconds

The volume of water that has been discharged through tributary B in 30 seconds = 28.012 m³/s * 1800 seconds = 50421.6 m³

Which are the methods used to seismically retrofit a building?

Answers

The methods used to seismically retrofit a building are: beam addition method, seismic wall addition method, support point adding method, and

seismic isolation method.

In construction of a building, seismically retrofitting or earthquake retrofitting is commonly done. The major reason to why it is done is to prevent displacement from the structure's foundation.

When seismically retrofitting is done, a building is considered safer and less likely to suffer damage when earthquake or any seismic forces strike.

So a retrofit is worth it as it will strengthen a building or an house against shake damage to help people living in it to remain safe and less worried. The following methods can therefore be used to provide a retrofit or to seismically retrofit a building:

Beam addition method

This is done by adding beams between the main girders of the existing reinforced concrete to improve the load carrying capacity of the reinforced concrete.

Seismic wall addition method

This is done by placing new reinforced concrete walls between existing ones and bonding them to improve load carrying capacity as a structural body

Support point adding method

This is done by supporting sections of beams and other existing concrete members with new members to reduce the span of members

Seismic isolation method

This is done by using seismic isolation bearings to reduce the seismic energy applied to the structure. This will improve the building's performance values during an earthquake.

Answers

Answer:

Explanation:

Hello,

In this case, for the inlet stream, from the steam table, the specific enthalpy and entropy are:

\(h_1=1456.0\frac{BTU}{lbm} \ \ \ s_1=1.6413\frac{BTU}{lbm*R}\)

Next, for the liquid-vapor mixture at the outlet stream we need to compute its quality by taking into account that since the turbine is adiabatic, the entropy remains the same:

\(s_2=s_1\)

Thus, the liquid and liquid-vapor entropies are included to compute the quality:

\(x_2=\frac{s_2-s_f}{s_{fg}}=\frac{1.6313-0.39213}{1.28448}=0.965\)

Next, we compute the outlet enthalpy by considering the liquid and liquid-vapor enthalpies:

\(h_2=h_f+x_2h_f_g=236.14+0.965*933.69=1136.9\frac{BTU}{lbm}\)

Then, by using the first law of thermodynamics, the maximum specific work is computed via:

\(h_1=w_{out}+h_2\\\\w_{out}=h_1-h_2=1456.0\frac{BTU}{lbm}-1136.9\frac{BTU}{lbm}\\\\w_{out}=319.1\frac{BTU}{lbm}\)

specimen,
assuming the specific gravity of the soil grains is 2.70.
(8)
[8 marks]

Answers

Explanation:

To find the degree of saturation of the clay specimen, we need to first calculate its volume and its dry mass.

The volume of the clay specimen can be calculated using its dimensions:

Volume = π/4 x diameter^2 x height

= π/4 x (125 mm)^2 x 210 mm

= 1640625 mm^3

= 1640.625 cm^3

Next, we can calculate the dry mass of the clay specimen:

Dry mass = Moist mass - Water mass

= 5184 g - 4631 g

= 553 g
