QUESTION:

A 3-m3 rigid tank contains hydrogen at 250 kPa and 550 K. The gas is now cooled until its temperature drops to 350 K. Determine (a) the final pressure in the tank and (b) the amount of heat transfer.

ANSWER:

Step 1 of 4

The hydrogen gas in a rigid tank is cooled until its temperature drops to . The final pressure in the tank and the amount of heat transfer are to be determined.

Assumptions are

1. Hydrogen is an ideal gas since it is at a high temperature and low pressure relative to its critical point values of and .

2. The tank is stationary, and thus the kinetic and potential energy changes are negligible, .

The gas constant of hydrogen is (Table A-1). The constant volume specific heat of hydrogen at the average temperature of is , (Table A-2).
