Specified Datal = length of pipe (ft) 11.5

120q = volume flow (gal/min) 40.7dh = inside or hydraulic diameter (inches) 1.25

Calculated Pressure Lossf = friction head loss in feet of water per 100 feet of pipe (ft H20 per 100 ft pipe) 48.03f = friction head loss in psi of water per 100 feet of pipe (psi per 100 ft pipe) 20.65

Head loss (ft H20) 5.52Head loss (psi) 2.38

Calculated Flow Velocityv = flow velocity (ft/s) 10.65
