An air-standard Diesel cycle has a compression ratio of 18.2. Air is at 120F and 14.7 psia at the beginning of the compression process and at 3200 R at the end of the heataddition process. Accounting for the variation of specific heats with temperature, determine (a) the cutoff ratio, (b) the heat rejection per unit mass, and (c) the thermal efficiency.

Question
An air-standard Diesel cycle has a compression ratio
of 18.2. Air is at 120F and 14.7 psia at the beginning of the
compression process and at 3200 R at the end of the heataddition
process. Accounting for the variation of specific heats with temperature, determine (a) the cutoff ratio, (b) the
heat rejection per unit mass, and (c) the thermal efficiency.
