The compression ratio of an air-standard Diesel Cycle is 17 and the conditions at the beginning of compression are p1 = 14.0 lbf/in², V1 = 2 ft³, and T1 = 520 degR. The maximum temperature in the cycle is 4000 degR. Calculate a) the net work for the cycle, in Btu b) the thermal efficiency c) the mean effective pressure, in lbf/in^2 d) the cutoff ratio
