An insulated rigid tank has two compartments, one 10 times larger than the other, divided by a partition. At the beginning the smaller side contains 4 kg of H2O at 200 kPa, 90oC and the other side is evacuated. The partition is removed and the water expands to a new equilibrium condition.
Determine the irreversibility during the process. Assume the surrounding conditions to be 100 kPa and 25oC.
What-if Scenario: What would the irreversibility be if the larger chamber were 100 times larger?
