Po Air R-22 FIGURE P4.31 4.31 A vertical cylinder (Fig. P4.31) has a 90-kg piston locked with a pin trapping 10 L of R-22 at 10°C, 90% quality inside. Atmospheric pressure is 100 kPa, and the cylinder cross-sectional area is 0.006 m². The pin is removed, allowing the piston Pin to move and come to rest with a final temperature of 10°C for the R-22. Find the fi- nal pressure, final volume, and work done by the R-22.
