- The Inner And Outer Diameters Of The Impeller Of A Centrifugal Pump Are 25 And 50 Cm Respectively The Pump Discharges 8 1 (35.61 KiB) Viewed 20 times
The inner and outer diameters of the impeller of a centrifugal pump are 25 and 50 cm respectively. The pump discharges 8 m? of water per minute while operating at 550 rpm against a head of 12 m. The diameter of the discharge outlet is 15 cm. The outlet diameter of the backward curved impeller vane is 40°. The flow area from the impeller inner to outer radius is constant and is equal to 750 cm? Draw the velocity triangles and calculate: i Inlet angle of the vane ii. Hydraulic efficiencies based on static head, and on total head. iji. Minimum speed for starting the pump in rpm.
