A Carnot refrigeration cycle is operating under the two phase region using 0.96 kg of refrigerant 134-a. The maximum absolute highest temperature of the cycle TH is 1.2 times the minimum absolute temperature TL. The net work is 22 KJ. The refrigerant changes from saturated vapor to saturated liquid during heat rejection process. Determine:

The space between two 15-in.-long concentric cylinders is filled with glycerin (viscosity = 8.5 × 10-3 lb·s/ft2). the inner cylinder has a radius of 1 in. and the gap width between cylinders is 0.1 in. determine (a) the torque and (b) the power required to rotate the inner cylinder at 180 rev/min. the outer cylinder is fixed. assume the velocity distribution in the gap to be linear.
