The centrifugal pump must provide a flow rate of Q = 0.1 m3/s and an outlet pressure p2 = 4.7•104 N/m2. The suction pipe has a diameter d = 0.3 m and a length L = 24 m, as well as an inlet filter with a local resistance coefficient e = 5. Water is suctioned from an open tank (Fig.). Friction loss coefficient L = 0.02, local resistance coefficient Erotation = 0.2. Determine the suction height Hvs.
