Unformatted text preview: pressure of 101 kPa. The system is taken through three processes, returning to its original state (this constitutes a cycle): state 1 --> state 2: gas is compressed in a polytropic process (pV n =const.) with n = 1.4 to half its original volume. state 2 --> state 3: gas is heated at constant pressure until it has expanded back to its original volume. state 3 --> state 1: gas is cooled at constant volume back to its original state. a) Sketch P-v diagram for the cycle. b) Find the work done in each process segment(1-->2, 2-->3, 3-->1). Is the work done positive or negative (done on or by the gas)? c) What is the net work for the cycle? d) What is the net heat for the cycle?...
