The ideal (theoretical) pressure increase across a centrifugal pump is 10m. The radial velocity through the pump is constant at 2m/s. The exit angle of the impeller vanes is 60 and the water enters radially. If whirl velocity at exit is 7.4m/s, ignoring friction and other losses calculate The peripheral velocity at the impeller exit in m/s The velocity head at the impeller exit
