Consider a modification of the air-standard otto cycle in which the isentropic compression and expansion processes are each replaced with polytropic processes having n = 1.35. the compression ratio is 12 for the modified cycle. at the beginning of compression, p1 = 1 bar and t1 = 310 k. the maximum temperature during the cycle is 2200 k. determine: (a) the heat transfer and work in kj per kg of air for each process in the modified cycle. (b) the percent thermal efficiency. (c) the mean effective pressure, in bar.
