QUESTION 2 [15] A centrifugal pump delivers water at 1.41 m³/min at a speed of 1450 rpm. The impeller has a diameter of 395 mm and the width of vanes at outlet is 12 mm. The pressure exerted between the inlet and outlet flanges is 284.5 kPa. The manometric efficiency of the pump is 74%. 2.1. Sketch correctly the complete velocity triangle and calculate The total pressure head 2.2. 2.3. The peripheral velocity of the impeller at outlet 2.4. 2.5. The radial flow velocity of the water leaving the impeller The tangential (whirl) velocity of the water leaving the impeller The outlet angle of the impeller vanes 2.6. (3)
