During the expansion process of the ideal Otto cycle the gas is a mixture whose volumetric composition is 25% nitrogen, 7 percent oxygen, 28% water and 40% carbondioxide. Calculate the thermal efficiency of this cycle when the air at the beginning of the compression is 12 psi and 55 F, the compression ratio is 7 and the maximumcycle temperature is 1600 F. Model the heat addition and heat rejection processes using constant gas properties (Cp and Cv) that are the average of the air and theexpansion gas properties. You may use Cp of Water to be (0 .445 Btu/lbm R)
