Supply Pipe Length(5.8) X 1.25=Equivalent Pipe Length <br /> 25 ft X 1.25 - 31.25 `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 /> 0.00 ft per 100ft x 31.25 ft + 100 = 0.00 ft <br />
