The displacement volume of an internal combustion engine is 5.6 liters. the processes within each cylinder of the engine are modeled as an air-standard diesel cycle with a cutoff ratio of 2.1. the state of the air at the beginning of compression is fixed by p1 = 95 kpa, t1 = 27°c, and v1 = 6.0 liters. determine (a) the net work per cycle, in kj, (b) the power developed by the engine, in kw, if the cycle is executed 1500 times per min (c) the thermal efficiency.
