A standard Carnot heat engine cycle is executed in a closed system between
the temperature limits of 320 and 1350 K, with air as the working fluid. The
pressures before and after the isothermal compression are 150 and 300
kPa, respectively. Sketch the TS diagram for this cycle.
If the net work output per cycle is 0.75 kJ, determine the efficiency of the
cycle and the heat transfer to the air
(working fluid) per cycle.
