1. A cylinder is divided by a frictionless, thermally insulated piston (which means that it doesn't allow any heat transfer). One compartment contains air and while the other contains water, as 140 F and the water is initially at 250 F and a quality of 22 percent. The cylinder is well shown in the schematic. Each compartment volume is initially at 7 ft'. The air is initially at insulated on all sides except for the end of one side with water where heat can be slowly transferred to the water. The heat transfer to the water stops when the water reaches a saturated vapor state at 90 psia. Calculate the amount of heat transfer in Btus, the final temperature for air in R, the entropy change for air in Btus/R, the entropy change for water in Btus/R. Is this process possible, if the surroundings are at 400 C? Thermally Insulated and Frictionless Piston Air HO Qinput
