Heat Transfer Extremely large or small volumes of fluids are generally best routed through the shell side of a shell and tube heat exchanger, because of the High heat transfer co-efficient Flexibility possible in the baffle arrangement Less corrosion problems Low pressure drop High heat transfer co-efficient Flexibility possible in the baffle arrangement Less corrosion problems Low pressure drop ANSWER DOWNLOAD EXAMIANS APP
Heat Transfer For the same heat load and mass flow rate in the tube side of a shell and tube heat exchanger, one may use multipass on the tube side, because it Decreases the outlet temperature of cooling medium Decreases the pressure drop None of these Increases the overall heat transfer coefficient Decreases the outlet temperature of cooling medium Decreases the pressure drop None of these Increases the overall heat transfer coefficient ANSWER DOWNLOAD EXAMIANS APP
