Data for a power cycle operating at steady state between reservoirs at 1200 and 400 K is given. For each scenario determine the net power developed in kW and the thermal efficiency. Using the analytical form of the Claudius inequalities determine whether the cycle operates reversibly, irreversibly or is impossible.
a) QH = 600 kW, QC = 400 kW
b) QH = 600 kW, QC = 0 kW
c) QH = 600 kW, QC = 200 kW
