A centrifugal pump with radial inlet (alpha4 = 90°) operates with
water at a flow of 0.3 m3
/s. The rotor diameter is 250 mm and the blades
it is 30 mm wide at the outlet. Assume that the blades are radial at the exit.
Determine the theoretical height considering infinite number of blades and power
required when the pump runs at 800 rpm.
A centrifugal pump impeller has an external diameter of 1.2 m and
internal diameter of 0.8 m. The width of the impeller at outlet is
0.175 m and the blade angle at outlet is 65 degrees. The flow
velocities at inlet and outlet are the same (Va1 = Va2). This pump
delivers 1.55 m3/s of water at 210 rpm. For theoretical
performance, calculate:
1-The flow velocity . 2-blade speed at outlet. 3-blade angle at inlet
(in degrees). 4-the developed head. 5-The pressure rise across the
impeller. 6-The number of blades . 7-The NPSH .
