For question 2-9, consider an air-standard cycle operating as a closed system with the following processes: Process 1-2: isentropic compression from 150 kPa and 30C with a compression ratio of V1 / V2 = 14 Process 2-3: constant volume heat addition until P3 = 7.0 MPa Process 3-4: constant pressure heat addition with v4 / V3 = 4 Process 4-5: isentropic expansion Process 5-1: constant volume heat rejection Note that the isentropic processes are adiabatic. Apply the cold air-standard assumptions, and the following constants: k = 1.400 Cp = 1.005 KJ/kg.K Cy = 0.718 KJ/kg.K R = 0.287 KJ/kg.K What is T2, the air temperature in State 2 (in K)?
