Pump Selection Design Worksheet <br />1. PUMP CAPACITY <br />1. Pumping to Gravity Distribution <br />A. Minimum discharge is 10 GPM (15 GPM recommended) <br />B. Maximum discharge is 45 GPM. <br />2. Pressure Distribution • See Pressure Distribution Worksheet <br />Required Flow Rate (Line 20 of Pressure Distribution Worksheet) <br />2.

Based on Friction Loss in Plastic Pipe per 100ft from Table I: <br />Friction Loss = I 0.48 <br />Ift per 100ft of pipe <br />1 ft 5ft <br />2ft 6ft <br />5ft = 10(t <br />7• 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 />Supply Pipe Length: <br />105 1 ft X 1.25 <br />8. Calculate Supply Friction Loss by multiplying Friction Loss Per 100ft (Line 6) by the <br />Equivalent Pipe Length (Line 7) and divide by 100. <br />Supply Friction Loss = <br />I0.48 1 ft per 100ft X I 131.25 Ift <br />131.25 I(t <br />100 = I 0.63 Ift <br />10. Total Head requirement is the sum of the Elevation Rifference (Line 3), the Distribution Head <br />Loss (Line 4), and the Supply Friction Loss (Line 8) <br />12 Ift <br />Total Heod Required: <br />3.
