instep 23, pressure decreases at constant volume to 2 bar, in step 34, volume decreases at constant pressure; and in step 41 . the gas returns adiabatically to its initial state.Take Cp = (7/2)R and Cv = (5/2)R. (a) Sketch the cycle on a PV diagram. (b) Determine (where unknown) both T and P for states 1. 2. 3. and 4. (c) Calculate Q. W, AU, and AH for each step of the cycle.
