1. PUMP CAPACITY <br />Selection required <br />1. If pumping to gravity enter the gallon per minute of the pump:GPM (10 - 45 gpm) <br />GPM <br />3. 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. <br />ft +ft +ft +ft = ft <br />GPM (Line 1 or Line 2) with at least feet of total head. <br />Determine Equivalent Pipe Length from pump discharge to soil dispersal area discharge <br />point. Estimate by adding 25% to supply pipe length for fitting loss. Supply Pipe Length <br />(D.2) X 1.25 = Equivalent Pipe Length <br />3. PUMP SELECTION <br />A pump must be selected to deliver at least 20.0 6.4 <br />Comments: <br />Total Head requirement is the sum of the Elevation Difference (Line A), the Distribution Head Loss (Line B), Additional Head Loss (Line C), and <br />the Supply Friction Loss (Line G ) <br />6.0 0 6.40.4 <br />32.5 0.4 <br />Friction Loss in Plastic Pipe per 100ft from Table I: <br />1.12 ft per 100ft of pipe <br />26 32.5 <br />Calculate Supply Friction Loss by multiplying Friction Loss Per 100ft (Line E) by the Equivalent Pipe Length (Line F) and divide by 100. <br />Supply Friction Loss = <br />1.12 <br /> <br />2.0 <br />26 <br />between pump and point of discharge: <br />Distribution Head Loss:0 <br />Additional Head Loss: <br />1.
