Repeat Prob. 6-131E when the supply line carries oxygen at 300 psia and 450°F.

Prob. 6-131.

The weighted piston of the device shown in Fig. P6-131E maintains the pressure of the piston-cylinder contents at 200 psia. Initially, this system contains no mass. The valve is now opened, and steam from the line flows into the cylinder until the volume is 10 ft3. This process is adiabatic, and the steam in the line remains at 300 psia and 450°F. Determine the final temperature (and quality if appropriate) of the steam in the cylinder and the total work produced as the device is filled.
