An engine operating on an ideal Diesel cycle has a cylinder volume when the piston is at bottom-dead-center (BDC), V1 = 1 liter = 0.001 m3. The intake pressure and temperature are P1 = 100 kPaand T1 = 300 K. The engine cycle contains the following processes: • Adiabatic compression toV1/25. • Constant pressure heating to V1/16. • Adiabatic expansion to V1. • Constant volume heatrejection back to P1, T1.The gas in the cylinder has the following fixed values of the specific heats; Cp = 1004.0 J/kg - K, andCv = 717 Jkg K. Perform the following analysis:a. Calculate pressure, temperature, and volume at each state point and enter in a table like the onebelow and make a sketch of the cycle on a P-V diagram. Label the cycle state points.b. What is the value of the cutoff ratio for this cycle, and the amount of heat added per cycle, Qin?c.
