Superheated steam enters a device at the rate of 22.1 lbm/sec with a velocity of 450 ft/s at 750 F and 1625

Superheated steam enters a device at the rate of 22.1 lbm/sec with a velocity of 450 ft/s at 750 F and 1625 psia. A fraction of the entering steam leaves the device with a velocity of 1470 ft/s at 50 F and a quality of 0.78 and a pipe diameter of 3.5 ft. The remaining steam leaves the device as saturated vapor at 141.41 F through a pipe of 1.5 ft in diameter. The loss of heat to the surroundings from the device is found to be 2,726 Btus/min. Determine: the net power of the device in kW and the exit velocity of the saturated vapor in ft/s. Also show and label the three states in a P-v and a T-v diagram.
