4. A reversible heat pump transfers heat from the air contained in a rigid tank A and rejects heat to the air contained in a rigid tank B as shown below. Initially both tanks contain 0.05 kmol of air at 200 kPa and 800 K. The heat pump operates until the air in tank A drops to 650 K.Cv of air is 20.785 J/mol.K. a) Calculate the final temperatures and pressures of tanks A and B. b) Calculate the work input to the heat pump. W ㅁㅁ A Heat Pump
