Heat Transfer In a shell and tube type heat exchanger, the floating tube bundle heat arrangement is used In low range of temperature differences To prevent corrosion of the tube bundles In high range of temperature differences Because of its low cost In low range of temperature differences To prevent corrosion of the tube bundles In high range of temperature differences Because of its low cost ANSWER DOWNLOAD EXAMIANS APP
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 4000 2000 5000 6000 4000 2000 5000 6000 ANSWER DOWNLOAD EXAMIANS APP
