Heat Transfer Extremely large or small volumes of fluids are generally best routed through the shell side of a shell and tube heat exchanger, because of the Less corrosion problems Flexibility possible in the baffle arrangement High heat transfer co-efficient Low pressure drop Less corrosion problems Flexibility possible in the baffle arrangement High heat transfer co-efficient Low pressure drop ANSWER DOWNLOAD EXAMIANS APP
Heat Transfer Bulk of the convective heat transfer resistance from a hot tube surface to the fluid flowing in it, is In the central core of the fluid None of these Uniformly distributed throughout the fluid Mainly confined to a thin film of fluid near the surface In the central core of the fluid None of these Uniformly distributed throughout the fluid Mainly confined to a thin film of fluid near the surface ANSWER DOWNLOAD EXAMIANS APP
Heat Transfer For the same heat load and mass flow rate in the tube side of a shell and tube heat exchanger, one may use multipass on the tube side, because it Decreases the pressure drop None of these Increases the overall heat transfer coefficient Decreases the outlet temperature of cooling medium Decreases the pressure drop None of these Increases the overall heat transfer coefficient Decreases the outlet temperature of cooling medium 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 5000 6000 4000 2000 5000 6000 4000 2000 ANSWER DOWNLOAD EXAMIANS APP
