a) A reversible heat engine operates between 700 K and 300 K and it derives refrigerator operating between 350 K and 1500 K. The engine receives 2000 KJ of heat and the net work output from this arrangement is 312 KJ. Draw this arrangement and calculate the cooling effect of refrigerator. b) Heat is transferred to 8 kg of air which is initially at at 120 kpa and 270 K until its temperature reaches 720 K. Determine the change in internal work done for constant Pressure Process . Assume that air is an ideal gas following PV=nRT.Cp=27.098KJ/Kmol , molecular weight of air is 29
