Process Equipment and Plant Design Weep holes provided in the plates of a distillation column Are normally located near the overflow weir so that any delivery of liquid during operation follows approximately the same path as the overflow fluid 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 All of these Are normally located near the overflow weir so that any delivery of liquid during operation follows approximately the same path as the overflow fluid 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 All of these ANSWER DOWNLOAD EXAMIANS APP
Process Equipment and Plant Design Pressure drop due to pipe fittings can be estimated by the equation, ΔP/p = 4f.Le/D.V2/2gc, where, Le = equivalent length of straight pipeline which will incur the same frictional loss as the fitting and D = diameter of the fitting. The value of Le/D (dimensionless) for 45° elbow and 180° close return bends would be respectively around 180 and 300 45 and 75 300 and 500 5 and 10 180 and 300 45 and 75 300 and 500 5 and 10 ANSWER DOWNLOAD EXAMIANS APP
