It is proposed to build a three- stage centrifugal pump to deliver 4000 kg/min of water at a speed of 900 rpm under a total manometric head of 70 m. The vanes are to be radial at inlet and are to be curved backwards at exit at an angle of 45°. Assuming manometric efficiency of 84% and overall efficiency of 75% and considering that vane thickness accounts for 8% of circumferential area. The velocity of flow may be assumed constant at 2.5 m/sec. The width of each impeller is ؟
