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
