T OR F? Sgen is greater than zero for reversible process

COP of a refrigerator is higher than COP of a heat pump operating between the same two reservoirs

The efficiency an irreversible heat engine is always lower than the efficiency of a reversible engine operating between the same two reservoirs.

Expert Solution

In reversible process,all the internal irreversibility are zero.So there will be no entropy generation.Hence statement 1 is false.

COP of Heat pump=COP of refrigerator +1

Therefore statement 2 is false

Statement 3 is true as it follows Carnot Principle.

You are installing a heat pump whose COP is half the COP of a reversible heat pump. You plan to use the pump on chilly winter nights to increase the air temperature in your bedroom. Your bedroom's dimensions are 5.35 m ? 3.6 m ? 2.7 m. The air temperature should increase from 63° F to 68° F. The outside temperature is 35° F, and the temperature at the air handler in the room is 112° F. If the pump's...
