The data listed below are claimed for a power cycle operating between hot and cold reservoirs at 500C and 10C, respectively. For each case, determine whether the cycle operates reversibly, operates irreversibly, or is impossible. (a) (b) QH = 70000J, Wcycle = 460 kJ, QC = 240 kJ QH = 600 kW, Wcycle = 16800 kJ/min, QC = 19200 kJ/min QH = 901.26 kJ, Wcycle = 570.5kJ, QC = 330.76 kJ QH = 800 kJ, Wcycle = 400kJ, QC = 400 kJ
