• An insoluble wet granular material is dried in a pan 0.457 x 0.457 m (1.5 x 1.5 ft) and 25.4 mm deep. The material is 25.4 mm deep in the pan, and the sides and bottom can be considered to be insulated. Heat transfer is by convection from an air stream flowing parallel to the surface at a velocity of 6.1 m/s (20 ft/s). The air is at 65.6°C (150°F) and has a humidity of 0.010 kg H,O/kg dry air. Estimate the rate of drying for the constant-rate period using SI and English units.

Transcribed Image Text:An insoluble wet granular material is dried in a pan
0.457 x 0.457 m (1.5 x 1.5 ft) and 25.4 mm deep.
The material is 25.4 mm deep in the pan, and the
sides and bottom can be considered to be insulated.
Heat transfer is by convection from an air stream
flowing parallel to the surface at a velocity of 6.1
m/s (20 ft/s). The air is at 65.6°C (150°F) and has a
humidity of 0.010 kg H,O/kg dry air. Estimate the
rate of drying for the constant-rate period using SI
and English units.
