Extracted text: 3. A centrifugal pump impeller runs at 1400 rpm, and vanes angle at exit is 25 degrees. The tangential velocity at exit is 29.33 m/s. Whirl velocity at impeller tip is 23.75 m/s. The impeller has an internal diameter of 0.2 m. Assuming a constant radial flow through the impeller at 2.6 m/s. Calculate: a. The vanes angle at exit b. The angle made by the absolute velocity of water at exit with tangent c. The inlet vane angle d. The work done per kg of water e. Draw the velocity triangle of the system f. Find the impeller external diameter
