An oil engine operating on the ideal diesel cycle has the overall compression ratio of 16:1, and the adiabatic expansion ratio or 8.75. The pressure and temperature at the beginning of adiabatic compression are 102.5 Kpa and 297K, respectively and the pressure at the end of the adiabatic expansion is 267kPa. If K=Cp/C=1.4, determine 1) the maximum temperature attained during the cycle, 2) thermal efficiency of the engine
