Air in an ideal Diesel cycle is compressed from 4 L to 0.25 L‚ and then it expands during the constant pressure heat addition process to 0.50 L. Under cold air standard conditions‚ determine the thermal efficiency of this cycle. 9. A Carnot heat engine receives heat at 800K and rejects the waste heat to the environment at 300K. The entire work output of the heat engine is used to drive a Carnot refrigerator that removes heat from the cooled space at -15oC at a rate of 400KJ/min
