A reversible cycle executed by 1 mol of an ideal gas for which CP= (5/2)R and CV= (3/2)R consists of the following: • Starting at T1 = 700 K and P1 = 1.5 bar, the gas is cooled at constant pressure to T2 = 350 K. • From 350 K and 1.5 bar, the gas is compressed isothermally to pressure P2. • The gas returns to its initial state along a path for which PT = constant. Determine the thermal efficiency of the cycle and compare this to the Carnot cycle operating between the minimum and maximum temperatures of the cycle. show the step and calculation.
