A solid material is dried in a dryer containing 50 trays, each tray deep is 0.01 m and area is 0.6 m², from 1 to 0.001 kg water/ kg dry solid. what is the drying time assume the heat is loss from top of tray only? Take: The air temperature is 350 K and the temperature of surface is 317 K Relative humidity across the trays is constant at 10 per cent Air velocity is 2 m/s Critical moisture of solid is 0.3 kg water/kg solid Density of the dry solid is 6000 kg/m³ convective coefficient of heat transfer is he =14.3Gº8 W/m².K, where G is is the mass velocity of the air in kg/m² s The latent heat of vaporization of water at 317 K is 2395 kJ/kg
