1. Saturated steam at a pressure of 25 psia is sprayed into a stream of moist air. The initial condition of the air is 55 dry-bulb temperature and 35 F de-point temperature. The mass rate of air flow is 2000 lb per min. Barometric pressure is 14.696 psia. Determine how much steam must be added in lb per min to produce a saturated air condition, b) the resulting temperature of the saturated air.
