Question

Water (density 1000=kg/m3) enters radially through a centrifugal pump whose impeller diameter has a diameter of 30 cm and breadth of 15 cm, the corresponding dimentions at the outer periphery are 60cm and 7.5 cm respectively. the blate angle at the outlet is 30 degree and the discharge is 225 lit/sec. the rotational speed of the impeller is 1200 rpm and the pump delivers water at a height of 115 m. if the overall and volumetric officiencies are 65% and 95% respectively, calcuate the theoretical head developed, mechanical efficiency and vane and blade angles at the inlet.
