2. An air-standard Diesel cycle has a compression ratio of 16 and a cutoff ratio of 2. At the beginning of compression, P = 14.2 lbf/in.2, V = 0.5 ft, and T =520 R. Calculate (a) the heat added, in Btu. (b) the maximum temperature in the cycle, in R. (c) the thermal efficiency. (d) the mean effective pressure, in lbf/in (e) To investigate the effects of varying compression ratio and cutoff ratio, plot each of the quantities calculated in parts (a) through (d) for compression ratios ranging from 5 to 18 and for cutoff ratios of 1.5, 2, and 2.5. Presentation tip: prepare 4 figures, separate for each property vs compression ratio; every figure will include 3 lines for different cutoff ratio values
