          Problem 5.4 An inventor claims the following power cycles for a system operating between hot and
cold reservoirs at temperatures 1200 K and 400 K, respectively. For each case, determine the (a) net
power $\dot{W}_{cycle}$ (in kW), (b) thermal efficiency ($\eta$ in %) and (c) nature ($\dot{\sigma}_{cycle}$) of the cycle.
1. $\dot{Q}_H$ = 600 kW, $\dot{Q}_C$ = 400 kW,
2. $\dot{Q}_H$ = 600 kW, $\dot{Q}_C$ = 200 kW.

Step 1

Step 1: Case 1: $\dot{Q}_H = 600$ kW, $\dot{Q}_C = 400$ kW (a) Net power: $\dot{W}_{cycle} = \dot{Q}_H - \dot{Q}_C = 600 - 400 = 200$ kW Show more…
