Thermodynamics Answer the following questions with complete solutions. write legibly An engine operates with air on the cycle shown with isentropic processes 1 - 2 and 3 - 4, and constant volume processes at 2 - 3 and 4 - 1. If the compression ratio (r) is 12, the minimum pressure is 200 kPa, and the maximum pressure is 10 MPa, determine the net cycle work (Wcycle) in terms of the final volume of isentropic compression process (V2). (Note: r = V1/V2 = V4/V3).
