In an engine working on Diesel cycle, inlet pressure and temperature are 1 bar and 17 C, respectively. Pressure at the end of adiabatic compression is 35 bar. The ratio of expansion, i.e. after constant pressure heat addition is 5. Calculate the heat addition, heat rejection and the efficiency of the cycle. Assume = 1.4, Cp = 1.004 kJ/kg K and cv = 0.717 kJ/kg K.
