The following particulars are related to a centrifugal pump, such as impeller diameter = 300 mm, width of impeller at its periphery = 50 mm, outlet vane angle = 30°, discharge = 0.2  m³/s, speed of the impeller = 1000 rpm, thickness of vanes occupies = 12% of the peripheral area and flow velocity = constant. Determine (i) the pressure rise in the impeller and (ii) percentage of total work converted to kinetic head.
