Outside air at 50°f, 1 atm, and 40% relative humidity enters an air-conditioning device operating at steady state. liquid water is injected at 45°f and a moist air stream exits with a volumetric flow rate of 1000 ft3/min at 90°f, 1 atm and a relative humidity of 40%. neglecting kinetic and potential energy effects, determine a. the rate water is injected, in lb/min.
