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 The corrosive and fouling fluid should be preferably routed through the tubes The viscous fluid should be routed through the shell side Higher pressure fluid stream should be routed through the shell side Lower flow rate fluid should be routed through the shell side The corrosive and fouling fluid should be preferably routed through the tubes The viscous fluid should be routed through the shell side Higher pressure fluid stream should be routed through the shell side ANSWER DOWNLOAD EXAMIANS APP

Process Equipment and Plant Design Heat transfer co-efficient, hG(Kcal/hr.m² .°C) and mass velocity of air, G (kg/hr.m² ) for air flow parallel to the surface in case of constant drying rate in batch drying is related as hG = 0.0176G0.8. But when the flow of air perpendicular to the surface is encountered, this equation changes to 0.0176G1.37 HG = 1.004G0.37 HG = 0.0176G0.37 1.004G0.8 0.0176G1.37 HG = 1.004G0.37 HG = 0.0176G0.37 1.004G0.8 ANSWER DOWNLOAD EXAMIANS APP
