1. Air is available at 70°F and humidity of 0.001lb/lb. It is to be treated to yield 130°F and 70% humidity. Offer a reasonable design.
2. A mix of granular ceramic material is to be dried in a rotary drier from X = 0.5 to 0.001 lb/lb where the solid is fed at 1000 lb/h dry basis and inlet temperature of 70°F. Hot and dry air at 200°F and 0.03 lb/lb humidity is available. The wet solid can be assumed to be at a constant drying regime. If U = 0.01m0.8 Btu/(hft2°F), calculate this constant drying rate. Calculate the area of transport.
