process cycle in aclosed system. From the initial state of 20 psia and 570 °R, the gas is
compressed at constant temperature to 1/5 of its initial volume, process 1-2; it is then
heated isochorically to state 3,process 2-3; and finally, it expands polytropically with index
n= 1.5 back to its initial state, process 3-1. Determine the pressures, specific volumes and
temperatures at cardinal points around the cycle and the cycle thermal efficiency.
