Ru = 8.31447 kJ/kmol.K

Rm = Ru/Mm (kJ/kg.K)0.146

Cp,m = (kJ/kg.K)1.153 (kJ/kg.K)

Cv,m = Cp,m - Rm (kJ/kg.K)1.007 (kJ/kg.K)

The ratio of specific heats for the mixture (k)

k= Cp,m/Cv,m (kJ/kg.K)1.145 (kJ/kg.K)

The Compession Ratio Engine (r)

r= 12.3

The temperature of engine

T1= 295 T4= 742

T2= T1*(r)^k-1 T3= 1067424.557
