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 Low pressure drop Flexibility possible in the baffle arrangement High heat transfer co-efficient Less corrosion problems Low pressure drop Flexibility possible in the baffle arrangement High heat transfer co-efficient Less corrosion problems ANSWER DOWNLOAD EXAMIANS APP
Heat Transfer The purpose of floating head in a heat exchanger is to Facilitate its lengthening, if needed Decrease the pressure drop Provide support for tubes Avoid buckling of tubes Facilitate its lengthening, if needed Decrease the pressure drop Provide support for tubes Avoid buckling of tubes ANSWER DOWNLOAD EXAMIANS APP
