Determine Equivalent Pipe Length from pump discharge to soil dispersal 70 --- --- --- 11.48 1.60 <br /> area discharge point. Estimate by adding 25%to supply pipe length for <br /> fitting loss. Supply Pipe Length(5.8) X 1.25=Equivalent Pipe Length <br /> 400 ft X 1.25 = 500 ft <br /> 8. Calculate Supply Friction Loss by multiplying Friction Loss Per 100ft (Line 6)by the Equivalent Pipe Length (Line 7)and divide by 100. <br /> Supply Friction Loss= <br /> 2,52 ft per 100ft x D§Eft + 100 = 12.60 ft <br />
