Heat Transfer The overall heat transfer co-efficient for a shell and tube heat exchanger for clean surfaces is U0 = 400 W/m².K. The fouling factor after one year of operation is found to be hd0 = 2000 W/m².K. The overall heat transfer co-efficient at this time is 287 W/m².K 333W/m².K 1200W/m².K 894W/m².K 287 W/m².K 333W/m².K 1200W/m².K 894W/m².K 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)-1.8 (D)-0.2 (D)0.2 (D)1.8 (D)-1.8 (D)-0.2 (D)0.2 ANSWER DOWNLOAD EXAMIANS APP
