Heat Transfer In an extended surface heat exchanger, fluid having lower co-efficient Flows through the tube Flows outside the tubes Should not be used as it gives very high pressure drop Can flow either inside or outside the tubes Flows through the tube Flows outside the tubes Should not be used as it gives very high pressure drop Can flow either inside or outside the tubes ANSWER DOWNLOAD EXAMIANS APP
Heat Transfer The variation of thermal conductivity of a metal with temperature is often correlated using an expression of the form K = K₀ + at. where, K is the thermal conductivity and T is the temperature (in °K). The units of 'a' in SI system will be W/m.k W/m.k² W/m None, A is just a number W/m.k W/m.k² W/m None, A is just a number ANSWER DOWNLOAD EXAMIANS APP
Heat Transfer Radiation heat transfer rates does not depend upon the surface area and temperature of the heat source type of absorbing surface none of the listed here distance between the heat source and the object receiving the heat surface area and temperature of the heat source type of absorbing surface none of the listed here distance between the heat source and the object receiving the heat 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 4000 2000 6000 5000 4000 2000 6000 ANSWER DOWNLOAD EXAMIANS APP
