Process Equipment and Plant Design Pick out the wrong statement about routing of fluids in a shell and tube heat exchanger. Lower flow rate fluid should be routed through the shell side Higher pressure fluid stream should be routed through the shell side The viscous fluid should be routed through the shell side The corrosive and fouling fluid should be preferably routed through the tubes Lower flow rate fluid should be routed through the shell side Higher pressure fluid stream should be routed through the shell side The viscous fluid should be routed through the shell side The corrosive and fouling fluid should be preferably routed through the tubes ANSWER DOWNLOAD EXAMIANS APP
