A process liquid is pumped from a storage tank to a distillation column, using a centrifugal pump. The pipeline is 80 mm internal diameter commercial steel pipe, 100 m long. Miscellaneous losses are equivalent to 600 pipe diameters. The storage tank operates at atmospheric pressure and the column at 1.7 bara. The lowest liquid level in the tank will be 1.5 m above the pump inlet, and the feed point to the column is 3 m above the pump inlet.
Plot the system curve on the pump characteristic given in Figure and determine the operating point and pump efficiency. Properties of the fluid: density 900 kg/m3, viscosity 1.36 mN m-2 s.
