Required information An ideal gas is contained in a piston-cylinder device and undergoes a power cycle as follows: 1-2 Isentropic compression from an initial temperature T₁= 20°C with a compression ratio r/= 6.5 2-3 Constant-pressure heat addition 3-1 Constant-volume heat rejection The gas has constant specific heats with cy= 0.7 kJ/kg-K and R = 0.3 kJ/kg-K. Choose the correct expression for the cycle thermal efficiency as a function of the compression ratio r and ratio of specific heats k
