Adv Refrigerant-22 is flowing in a pipeline at 40 F, 80 lbf/in 2, with a velocity of 650 ft/s, at a steady flow rate of 0.2 lbm/s, tt is desired to decelerate the fluid and increase its pressure by installing a diffuser in the line (a diffuser is basically the opposite of a nozzle in this respect). The R-22 exits the diffuser at 80 F, with a velocity of 160 ft/s. It may be assumed that the diffuser process is SSSF, polytropic, and internally reversible. Determine the diffuser exit pressure and the rate of irreversibility for the process.
