The conditions at the beginning of compression in an Otto engine operating are 14.5 psia, 100 F. At the end of isentropic compression, the pressure is 352 psia, while the pressure is 1100 psia at the end of combustion. Find (a) T3, (b) e, and (c) if the sink temp is 100 F what percentage of the available part of the heat added was utilized?
