The impeller of a centrifugal pump has an internal diameter of 200 mm and external diameter 400 mm. The widths of the impeller at entry and exit are 20 mm and 10 mm respectively. The discharge of water through the impeller is 20L/s. The impeller rotates at 1440 rpm and the blade angle at the outlet is 30 degrees. Determine the pressure head rise in the impeller neglecting friction losses.
