Process Equipment and Plant Design In a shell and tube heat exchanger for a given heat transfer surface area, smaller diameter tubes are favoured as compared to larger diameter ones ; because the smaller diameter tubes Are easier to clean None of these Can be fitted into a smaller shell diameter hence the cost of the heat exchanger would be less Are less prone to fouling Are easier to clean None of these Can be fitted into a smaller shell diameter hence the cost of the heat exchanger would be less Are less prone to fouling ANSWER DOWNLOAD EXAMIANS APP
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 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 Are normally located near the overflow weir so that any delivery of liquid during operation follows approximately the same path as the overflow fluid Facilitate draining out liquid from a tray when the unit is not in operation 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 Are normally located near the overflow weir so that any delivery of liquid during operation follows approximately the same path as the overflow fluid ANSWER DOWNLOAD EXAMIANS APP
