A power cycle operating at steady state receives energy by heat transfer at a rate Q_H at T_H = 1800 K and rejects energy by heat transfer to a cold reservoir at a rate Q_C at T_C = 600 K. For each of the following cases, determine whether the cycle operates reversibly, operates irreversibly, or is impossible.
Q._H = 500 kW, Q._C = 100 kW
Q._H = 500 kW, W._cycle = 250 kW,
Q._C = 200 kW W_cycle = 350 kW,
Q._C = 150 kW Q._H = 500 kW, Q._C = 200 kW
