Heat Transfer In a laboratory test run, the rate of drying was found to be 0.5 x 10-3 kg/m².s, when the moisture content reduced from 0.4 to 0.1 on dry basis. The critical moisture content of the material is 0.08 on a dry basis. A tray dryer is used to dry 100 kg (dry basis) of the same material under identical conditions. The surface area of the material is 0.04 m²/kg of dry solid. The time required (in seconds) to reduce the moisture content of the solids from 0.3 to 0.2 (dry basis) is 2000 5000 6000 4000 2000 5000 6000 4000 ANSWER DOWNLOAD EXAMIANS APP
Heat Transfer In an extended surface heat exchanger, fluid having lower co-efficient Can flow either inside or outside the tubes Should not be used as it gives very high pressure drop Flows through the tube Flows outside the tubes Can flow either inside or outside the tubes Should not be used as it gives very high pressure drop Flows through the tube Flows outside the tubes ANSWER DOWNLOAD EXAMIANS APP
