Answer:


And replacing in the Carnot efficiency we got:


Explanation:
For this case we can use the fact that the maximum thermal efficiency for a heat engine between two temperatures are given by the Carnot efficiency:

We have on this case after convert the temperatures in kelvin this:


And replacing in the Carnot efficiency we got:

And the maximum power output on this case would be defined as:

Where
represent the heat associated to the deposit with higher temperature.
Answer:
......................................................
Answer:
A.) 0.08 kJ/kg.K
B.) 207.8 KJ/Kg
C.) 0.808
Explanation:
From the question, the use of fluids mechanic table will be required. In order to get the compressor processes, the kinetic energy and the potential energy will be negligible while applying the ideal gas model.
Since the steam is a closed system, the carbon dioxide will be compressed adiabatically.
