Problem 98P

Using Generalized Compressibility Data

Five lbmol of carbon dioxide (CO2), initially at 320 lbf/in.2, 660°R, is compressed at constant pressure in a piston-cylinder assembly. For the gas, W = −2000 Btu. Determine the final temperature, in °R.

Solution 98P

Step 1 of 3

For a 5 lb mol of undergoes a constant pressure compression process in a piston cylinder assembly . The work , pressure and initial gas temperature are known , so here we need to find the final temperature.

Let us assume that the is a closed system and the pressure remains constant during the compression process.

Given,
