Arigid container is filled with a saturated vapor (steam) at a pressure of p 2 mpa. the steam is cooled until the pressure drops to p2 950 kpa. the volume of the container is 1 m3. a. find the final mass of vapor, mg, and liquid, m b. find the heat transferred from the steam. c. find the work done by the steam.

An air compression refrigeration system is to have an air pressure of 100 psia in the brine tank and an allowable air temperature increase of 60°f for standard vapor compression cycle temperatures of 77 f entering the expansion cylinder and 14 f entering the compression cylinder, calculate the coefficient of performance a. 2.5 b 3.3 c. 4.0 d. 5.0
