A centrifugal water pump designed to operate at \(1300 \mathrm{rpm}\) has dimensions

Draw the inlet velocity diagram for a volume flow rate of \(35 \mathrm{~L} / \mathrm{s}\). Determine the inlet blade angle for which the entering velocity has no tangential component. Draw the outlet velocity diagram. Determine the outlet absolute flow angle (measured relative to the normal direction). Evaluate the hydraulic power delivered by the pump if its efficiency is 75 percent. Determine the head developed by the pump.
