A centrifugal pump rotates at 750rpm. Water enters the impeller normal to the blades and exits at an angle of 35 from radial. The inlet radius is 12.0cm, at which the blade width is 18cm. The outlet radius is 24cm, at which the blade width is 16.2cm. The volume flow rate is 0.573m3/s. Assuming 100% efficiency, calculate the net head produced by this pump in cm of water column height. Also calculate the required brake horsepower in W
