An engine based on the Stirling cycle uses 2.2 kg of N; as its working fluid. 570 kJ of heat enters at a temperature of 850 K during each cycle. Heat is exhausted at 330 K. You may neglect the temperature dependence of the specific heat in this problem. What is the maximum amount of work that can be obtained per cycle?
