Unformatted text preview: and plot them on the first copy of your pump curve. Be sure to report the flowrate, operating head, diameter of the impeller and efficiency for each pump station. Note that the flow rate on the pump curve, which is the bottom of the page if you print it in landscape, is in gpm. (B) Plot the total dynamic head (TDH) system curve on separate pump curve figures for each station pumping alone and determine the operating points for the appropriate impeller diameter. Be sure to report the flowrate, operating head, impeller diameter and efficiency for each pump station. (C) Check the velocities of all sections to see if they fall within an acceptable range (2.5 to 5 ft/s.); otherwise, resize the pipe to comply with the desired velocities. DO NOT REDO THE PROBLEM.
