In an industrial dryer operating at steady state, atmospheric air at 80°F, 1 atm, and 65% relative humidity is first heated to 280°F at constant pressure. The heated air is then allowed to pass over the materials being dried, exiting the dryer at 150°F, 1 atm, and 30% relative humidity. If moisture is to be removed from the materials at a rate of 2700 lb/h, determine

(a) the mass flow rate of dry air required, in lb/h.

(b) the rate of heat transfer to the air as it passes through the heating section, in Btu/h. Neglect kinetic and potential energy effects.
