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 . %3D

- A centrifugal pump with an impeller diameter of 350mm and specific speed of 19.15 and requires 15 kW to discharge 2.4 m³ /min of water, and runs at 1800 rpm. Determine the discharge, head and power required when the pump runs at 2400 rpm. The same discharge could be obtained by altering the impeller diameter without changing the rotational speed for this case find the new diameter of the impeller the head and the power required.
Problem-3: A centrifugal pump lifts water against a static head Az = EN m. The pipe setup has a constant diameter of 0.08 m, major losses in the suction side h, = EN3 m and in the discharge side hLD is 3 m. The pump impeller has a diameter of 0.15 m, exit width of 0.015 m, exit blade angle of 22° and speed of N = 20EN rpm. The hydraulic efficiency is 0.85.
