A dryer operating is at steady state. Damp fabric containing 50%
moisture by mass enters on a conveyor and exits with a moisture
content of 4% by mass. The total mass of the fabric and water exits
at a rate of 323 lb/h. Dry air at 150°F, 1 atm enters, and moist
air at 130°F, 1 atm, and 30% relative humidity exits.
(c) Determine the mass flow rate of water entering with the
fabric.
(d) Determine the mass flow rate of water leaving the fabric and
entering the air stream.
(e) Look up the saturated partial pressure of water at the exit
air temperature, Pg.
(f) Determine the partial pressure of water in the exit air
stream, Pv.
(g) Determine the absolute humidity of exit air stream, ω.
(h) Determine the required mass flow rate of dry air.
