An insulated rigid tank is divided into two
Chapter 8, Problem 840(choose chapter or problem)
An insulated rigid tank is divided into two equal parts by a partition. Initially, one part contains 3 kg of argon gas at 300 kPa and 708C, and the other side is evacuated. The partition is now removed, and the gas fills the entire tank. Assuming the surroundings to be at 258C, determine the exergy destroyed during this process.

QUESTION:
An insulated rigid tank is divided into two equal parts by a partition. Initially, one part contains 3 kg of argon gas at 300 kPa and 708C, and the other side is evacuated. The partition is now removed, and the gas fills the entire tank. Assuming the surroundings to be at 258C, determine the exergy destroyed during this process.
ANSWER:Step 1 of 4
One side of a partitioned insulated rigid tank contains argon gas at a specified temperature and pressure while the other side is evacuated. The partition is removed, and the gas fills the entire tank. The exergy destroyed during this process is to be determined.
We assume that Argon is an ideal gas with constant specific heats, and thus ideal gas relations apply. The gas constant of argon is (Table A-1).
