A 1.5-ft³rigid tank contains saturated refrigerant-134 at 170 psia. Initially, 20 percent of the volume is occupied by liquid and the rest by vapor. A valve at the top of the tank is now opened, and vapor is allowed to escape slowly from the tank. Heat is transferred to the refrigerant such that the pressure inside the tank remains constant. The valve is closed when the last drop of liquid in the tank is vaporized. Determine the total heat transfer for this process. R-134a, Sat. mixture P = 170 psia V = 1.5 ft³

3 A tank contains 100 gal of brine in which 50 lb of salt is dissolved. Brine containing 2 lb/gal of salt runs into the tank at the rate of 3 gal/min; and the mixture, assumed to be kept uniform by stirring, runs out at the rate of 2 gal/min. Assuming that the tank is sufficiently large to avoid overflow, find the amount of salt in the tank as a function of the time t. When will the con- centration of salt in the tank reach Ib/gal? How much salt is in the tank at the end of 30 min? Work Exercise 3 with the rates of influx and efflux interchanged, and find the amount of salt in the tank after 1 h instead of at the end of 30 min. Under these circumstances, when will the 4 tank contain the maximum amount of salt, and what is this amount?
