Determine the mean effective pressure of an ideal Otto cycle that uses air as the working fluid if its state at the beginning of the compression is 13 psia and 60°F, its temperature at the end of the combustion is 1500°F, and its compression ratio is 9. Use constant specific heats at room temperature. The properties of air at room temperature are R = 0.3704 psia-ft³/lbm-R, cp = 0.240 Btu/lbm-R, cv= 0.171 Btu/lbm-R, and k = 1.4. The mean effective pressure is psia.
