Answer:
Explanation:
Let assume that air behaves ideally. The equation of state of ideal gases is:
Where:
- Pressure, in kPa.
- Volume, in m³.
- Quantity of moles, in kmol.
- Ideal gas constant, in .
- Temperature, in K.
Since there is no changes in pressure or the quantity of moles, the following relationship between initial and final volumes and temperatures is built:
The final temperature is:
The magnitude of the work done to push the object is 90,000 J
<h3>
When is Work done on a body ?</h3>
Work is done on a body when the direction of the force applied is parallel to the direction of the displacement of the body.
The following parameters are given;
First convert the distance in kilometer to meter by multiplying it by 1000
S = 1.2 x 1000 = 1200 m
From the definition of work,
W = F x S
Substitute the parameters into the formula
W = 75 x 1200
W = 90,000 J
Therefore, the magnitude of the work done to push the object is 90,000 J

Answer:
Rate of heat transfer will be 10.69 kw
Explanation:
We have given temperature
From standard table enthalpy of vaporization 2382.75 KJ/kg
Steam is coming out from turbine at rate of 16.154 kg/hour
We have to calculate the rate of heat transfer
Heat transfer is equal to
So rate of heat transfer
=
So rate of heat transfer will be 10.69 kw
