The compression ratio of dual combustion cycle is 14 and the maximum temperature is limited to 1850°C. If the working substance receives equal amount of heat during both constant volume and constant pressure process, determine the air standard efficiency of the cycle. Assume temperature at the start of the cycle is 27°C.
