The figure shows a dryer operating at steady state. Damp fabric
containing 50% moisture by mass enters on a conveyor and exits with
a moisture content of 6% by mass. The total mass of the fabric and
water exits at a rate of 437 lb/h. Dry air at 150°F, 1 atm
enters, and moist air at 130°F, 1 atm, and 60% relative humidity
exits.
(a) Determine the partial pressure of water in the exit air
stream, Pv.
(b) Determine the absolute humidity of exit air stream, ω.
(c) Determine the required mass flow rate of dry air.
