Heat Transfer Fresh orange juice contains 12% (by weight) solids and the rest water 90% of the fresh juice is sent to an evaporator to remove water and subsequently mixed with the remaining 10% of fresh juice. The resultant product contains 40% solids. The kg of water removed from 1 kg fresh juice is 0.6 0.7 0.4 0.5 0.6 0.7 0.4 0.5 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)-0.2 (D)1.8 (D)0.2 (D)-1.8 (D)-0.2 (D)1.8 (D)0.2 (D)-1.8 ANSWER DOWNLOAD EXAMIANS APP
