Heat Transfer Crystallisation of solids from a homogeneous solution is a/an __________ process. Highly endothermic Exothermic None of these Mildly endothermic Highly endothermic Exothermic None of these Mildly endothermic 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 2000 6000 4000 5000 2000 6000 4000 5000 ANSWER DOWNLOAD EXAMIANS APP
Heat Transfer In a shell and tube heat exchanger, There is no relationship between temperature drop and resistance The temperature drop is inversely proportional to the resistance across which the drop occurs The relationship is not generalised The temperature drops in the two fluids and the wall are proportional to individual resistances There is no relationship between temperature drop and resistance The temperature drop is inversely proportional to the resistance across which the drop occurs The relationship is not generalised The temperature drops in the two fluids and the wall are proportional to individual resistances ANSWER DOWNLOAD EXAMIANS APP
