Consider the power plant cycle in the figure at steady state . Air enters the compressor with a mass flow rate of 10kg / s at bar and 300 K and exits the turbine at bar 500 K. Heat input at an amount of 300kJ / k * g to the air occurs from a hot reservoir at 800 K. Compressor and turbine operate adiabatically .

Determine the maximum theoretical value for the net power that can be developed by the plant in MW. Hint : assume that the cold reservoir temperature is 300 K.

b. Determine the actual thermal efficiency of the cycle .

c. What is the overall change in the entropy of the cycle (i.e. Delta S cycle =?) ?
