Heat Transfer 1000 Kg of liquid at 30°C in a well stirred vessel has to be heated to 120°C, using immersed coils carrying condensing steam at 150°C. The area of the steam coils is 1.2 m² and the overall heat transfer co-efficient to the liquid is 1500 W/m².°C. Assuming negligible heat loss to the surrounding and specific heat capacity of the liquid to be 4 kJ/kg.°C, the time taken for the liquid to reach desired temperature will be 44 min 22 min 15 min 51 min 44 min 22 min 15 min 51 min ANSWER DOWNLOAD EXAMIANS APP
Heat Transfer Extended heat transfer surface like fins are used to increase the heat transfer rate. Fin efficiency is defined as the ratio of heat transferred across the fin surface to the theoretical heat transfer across an equal area held at the Temperature of the fin end Average temperature of the fin Surrounding temperature Constant temperature equal to that of the base Temperature of the fin end Average temperature of the fin Surrounding temperature Constant temperature equal to that of the base ANSWER DOWNLOAD EXAMIANS APP
