Moist air enters a dehumidifier at 808F, 1 atm, and f 5 60% and exits at 588F, 1 atm, and f 5 90% with a volumetric flow rate of 10,000 ft3/min. The stream then mixes adiabatically with a moist air stream at 958F, 1 atm, and f 5 47% having a volumetric flow rate of 2000 ft3/min. A single moist-air stream exits the mixing chamber. Stray heat transfer and kinetic and potential energy effects can be ignored. Determine at steady state
(a) the rate water is removed from the moist air passing through the dehumidifier, in lb/h.
(b) the temperature, in 8F, and the relative humidity of the moist air at the mixing chamber exit.
