1. PUMP CAPACITY v 04.01.2020 <br />A.If pumping to gravity enter the gallon per minute of the pump: GPM (10 - 45 gpm) <br />B.GPM <br />C.Enter pump description: <br />A.ft <br />B.ft <br />C. <br />D.in <br />ft <br />E. <br />Friction Loss = <br />F. <br />ft X 1.25 = ft <br />G. <br />ft per 100ft X ft ÷ 100 = ft <br />H.Total Head requirement is the sum of the Elevation Difference + Distribution Head Loss, + Additional Head Loss + Supply Friction Loss <br />ft + ft + ft + ft = ft <br />GPM with at least feet of total head. <br />Determine Equivalent Pipe Length from pump discharge to soil dispersal area <br />discharge point. Estimate by adding 25% to supply pipe length for fitting loss. <br />Supply Pipe Length X 1.25 = Equivalent Pipe Length <br />3.
