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
Heat Transfer The Sieder-Tate correlation for heat transfer in turbulent flow in pipe gives Nu α Re0.8, where, Nu is the Nusselt number and Re is the Reynolds number for the flow. Assuming that this relation is valid, the heat transfer co-efficient varies with the pipe diameter (D) as (D)1.8 (D)-0.2 (D)0.2 (D)-1.8 (D)1.8 (D)-0.2 (D)0.2 (D)-1.8 ANSWER DOWNLOAD EXAMIANS APP
