The impeller of a centrifugal pump is of 300 mm diameter and 50 mm width at the periphery, and has blades whose tip angle inclined backwards 60° from the radius. the pump delivers 17 m³/min. of water and the impeller rotates at 1000 r.p.m. assuming that the pump is designed to admit radially, calculate:
speed and direction of water as it leaves the impeller
