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 5 and 10 45 and 75 300 and 500 180 and 300 5 and 10 45 and 75 300 and 500 180 and 300 ANSWER DOWNLOAD EXAMIANS APP
Process Equipment and Plant Design Pick out the wrong statement about routing of fluids in a shell and tube heat exchanger. Higher pressure fluid stream should be routed through the shell side Lower flow rate fluid 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 Higher pressure fluid stream should be routed through the shell side Lower flow rate fluid 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
