Process Equipment and Plant Design Weep holes provided in the plates of a distillation column Facilitate draining out liquid from a tray when the unit is not in operation Are normally located near the overflow weir so that any delivery of liquid during operation follows approximately the same path as the overflow fluid All of these Must be large enough (usually 1/4" to 5/8" dia) to prevent plugging but should not deliver excessive amount of fluid during operation Facilitate draining out liquid from a tray when the unit is not in operation Are normally located near the overflow weir so that any delivery of liquid during operation follows approximately the same path as the overflow fluid All of these Must be large enough (usually 1/4" to 5/8" dia) to prevent plugging but should not deliver excessive amount of fluid during operation 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 HG = 0.0176G0.37 1.004G0.8 HG = 1.004G0.37 0.0176G1.37 HG = 0.0176G0.37 1.004G0.8 HG = 1.004G0.37 0.0176G1.37 ANSWER DOWNLOAD EXAMIANS APP
