Power Cycle ApplicationsThe data listed below are claimed
Chapter 5, Problem 17P(choose chapter or problem)
The data listed below are claimed for a power cycle operating between hot and cold reservoirs at 1000 K and 300 K, respectively. For each case, determine whether the cycle operates reversibly, operates irreversibly, or is impossible.
(a) \(Q_{\mathrm{H}}=600 \mathrm{\ kJ}, W_{\text {cycle }}=300 \mathrm{\ kJ}, Q_{\mathrm{C}}=300 \mathrm{\ kJ}\)
(b) \(Q_{\mathrm{H}}=400 \mathrm{\ kJ}, W_{\text {cycle }}=280 \mathrm{\ kJ}, Q_{\mathrm{C}}=120 \mathrm{\ kJ}\)
(c) \(Q_{\mathrm{H}}=700 \mathrm{\ kJ}, W_{\text {cycle }}=300 \mathrm{\ kJ}, Q_{\mathrm{C}}=500 \mathrm{\ kJ}\)
(d) \(Q_{\mathrm{H}}=800 \mathrm{\ kJ}, W_{\text {cycle }}=600 \mathrm{\ kJ}, Q_{\mathrm{C}}=200 \mathrm{\ kJ}\)
