Heat Transfer In a shell and tube heat exchanger, There is no relationship between temperature drop and resistance The temperature drops in the two fluids and the wall are proportional to individual resistances The temperature drop is inversely proportional to the resistance across which the drop occurs The relationship is not generalised There is no relationship between temperature drop and resistance The temperature drops in the two fluids and the wall are proportional to individual resistances The temperature drop is inversely proportional to the resistance across which the drop occurs The relationship is not generalised ANSWER DOWNLOAD EXAMIANS APP
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 51 min 15 min 22 min 44 min 51 min 15 min 22 min ANSWER DOWNLOAD EXAMIANS APP
