An insulated, rigid tank has two compartments, one 8 times as large as than the other, divided by a partition. At the beginning, the smaller side contains 4 kg of H2O at 200 kPa, 90 ∘C, and the other side is evacuated. The partition is removed and the water expands to a new equilibrium condition. Assume the surrounding conditions to be 100 kPa and 30 ∘C.  Part A. Determine the irreversibility during the process. Part B. What-if scenario: What would the irreversibility be if the larger chamber was 80 times larger?

Question

An insulated, rigid tank has two compartments, one 8 times as large as than the other, divided by a partition. At the beginning, the smaller side contains 4 kg of H2O at 200 kPa, 90 ∘C, and the other side is evacuated. The partition is removed and the water expands to a new equilibrium condition. Assume the surrounding conditions to be 100 kPa and 30 ∘C. 

Part A. Determine the irreversibility during the process.

Part B. What-if scenario: What would the irreversibility be if the larger chamber was 80 times larger?
 
Expert Solution
Step 1

Part (A):

Write the given data.

For smaller side,m1=4 kgP1=200 kPaT1=90 °CFor surrounding,Psurr=100 kPaTsur=30 °CAnd,V2=8V1
