A power cycle operates between two thermal reservoirs at 1200 K and 400 K, respectively. For each of the three cases below, determine: (i) The net power produced by the cycle, in kW; (ii) The thermal efficiency; and (iii) Use the Clausius inequality and comparisons to the thermal efficiency of a reversible cycle operating between the given temperatures to determine whether the cycle operates in a reversible or irreversible manner, or is impossible. case | QH(kJ/s) | QL(kJ/s) A | 600 | 400 B | 600 | 0 C | 600 | 200

Question
A power cycle operates between two thermal reservoirs at 1200 K and 400 K, respectively. For each of
the three cases below, determine: (i) The net power produced by the cycle, in kW; (ii) The thermal
efficiency; and (iii) Use the Clausius inequality and comparisons to the thermal efficiency of a reversible
cycle operating between the given temperatures to determine whether the cycle operates in a
reversible or irreversible manner, or is impossible.
case | QH(kJ/s) | QL(kJ/s)
A | 600 | 400
B | 600 | 0
C | 600 | 200
