(solution) A diesel cycle has a compression ratio of 20, and the heat input

A diesel cycle has a compression ratio of 20, and the heat input qin to the working fluid is 1600 kJ/kg. The Diesel cycle is unthrottled, so at the start of compression P1 = 101 kPa and T1 = 298K. Assuming the working fluid is air with constant properties, what is the maximum pressure and temperature in the cycle, the cycle efficiency, and imep?
