A submersible pump is to be selected for the installation on a newly drilled deep well. The static water level (SWL) of the water inside the well is 8.7m from the natural ground level and the centerline of the discharge pipeline is 3.5 feet above the natural ground level. Based on the test pumping results from the SWL the flow velocity at the pipeline discharge was 8.09 ft/s and the design pressure is 40 psi to assure that the water can reach the elevated water tank. The total head losses are assumed to be 12 feet. a.) Find the total dynamic head (TDH) of the submersible pump needed for sizing in feet ?

Question

A submersible pump is to be selected for the installation on a newly drilled deep well. The static water level (SWL) of the water inside the well is 8.7m from the natural ground level and the centerline of the discharge pipeline is 3.5 feet above the natural ground level. Based on the test pumping results from the SWL the flow velocity at the pipeline discharge was 8.09 ft/s and the design pressure is 40 psi to assure that the water can reach the elevated water tank. The total head losses are assumed to be 12 feet.

a.) Find the total dynamic head (TDH) of the submersible pump needed for sizing in feet ?

b.) What will be the suitable pipe diameter for the system riser in inches?
