Heat Transfer Log mean temperature difference (LMTD) cannot be used, if none of the listed here there exists an unsteady state the heat capacity is not constant and there is a phase change. heat transfer co-efficient over the entire heat exchanger is not constant none of the listed here there exists an unsteady state the heat capacity is not constant and there is a phase change. heat transfer co-efficient over the entire heat exchanger is not constant ANSWER DOWNLOAD EXAMIANS APP
Heat Transfer In an extended surface heat exchanger, fluid having lower co-efficient Can flow either inside or outside the tubes Should not be used as it gives very high pressure drop Flows through the tube Flows outside the tubes Can flow either inside or outside the tubes Should not be used as it gives very high pressure drop Flows through the tube Flows outside the tubes ANSWER DOWNLOAD EXAMIANS APP
