aturated steam at a pressure of 25 psia is sprayed into a stream of moist air. the initial condition of the air is 55 f db and 35 f dew point. the mass rate of air flow is 2000 lbma/min (remember that is dry air). assume standard atmospheric pressure. determine how much steam should be added in lbm/min to produce a saturated air condition and determine the resulting temperature of the saturated air.
