Four step mechanically reversible cycle in a closed system

Reference no: EM13164574

an ideal gas initally at 600 K and 10 bar undergoes a four step mechanically reversible cycle in a closed system. In step 1-2, pressure decreases isothermally to 3 bar; in step 2-3, pressure decreases at a constant volume to 2 bar; in step 3-4, volume decreases at constant pressure, and in step 4-1 the gas returns adiabatically to its initial state. Take Cp = (7/2)R and Cv = (5/2)R. a) determine (where unknown) both T and P for states 1,2,3,4 ..... b) calculate Q W dU and dH for each step of the cycle
