Example: In an ideal Diesel cycle the pressure and temperature at the beginning of the adiabatic compression are 98.5 kN/m2 and 60 °C respectively. The maximum pressure attained during the cycle is 4.5 MN/m² and the heat received during the cycle is 580 kJ/kg. Take y = 1.4 and R = 0.287 kJ/kg K. Determine: a) The temperature at the end of heat reception. c) The net work done per kilogram of gas. b) The heat rejected. d) The thermal efficiency. f) The mean effective pressure. e) The work ratio.
