The air in the tank of Problem 6.88 receives heat transfer from a reservoir at 450 K.

Question:

The air in the tank of Problem 6.88 receives heat transfer from a reservoir at 450 K. Find the entropy generation due to the process from 1 to 3.

Data from Problem 6.88

Air in a rigid tank is at 100 kPa, 300 K with a volume of 0.75m3. The tank is heated to 400 K, state 2. Now one side of the tank acts as a piston, letting the air expand slowly at constant temperature to state 3 with a volume of 1.5 m3. Find the entropy at states 1, 2, and 3.
