The steady-state data listed below are claimed for a power
Chapter 5, Problem 5.88(choose chapter or problem)
The steady-state data listed below are claimed for a power cycle operating between hot and cold reservoirs at 1200 K and 400 K, respectively. For each case, evaluate the net power developed by the cycle, in kW, and the thermal efficiency. Also in each case apply Eq. 5.13 on a time-rate basis to determine whether the cycle operates reversibly, operates irreversibly, or is impossible.
(a) \(\dot{Q}_{\mathrm{H}}=600 \mathrm{\ kW}, \dot{Q}_{\mathrm{C}}=400 \mathrm{\ kW}\)
(b) \(\dot{Q}_{\mathrm{H}}=600 \mathrm{\ kW}, \dot{Q}_{\mathrm{C}}=0 \mathrm{\ kW}\)
(c) \(\dot{Q}_{\mathrm{H}}=600 \mathrm{\ kW}, \dot{Q}_{\mathrm{C}}=200 \mathrm{\ kW}\)
