WebAccording to Darcy's formula, the loss of head due to friction in the pipe (hf) is given by where f = Darcy's coefficient, l = Length of pipe, v = Mean velocity of liquid in pipe, and d = Diameter of pipe. The major loss of head or energy is due to friction. The minor loss of head includes the following cases: WebStep 3. Calculate the static head loss based on 100 feet of elevation. The conversion factor for water at normal ambient conditions of 60 degrees Fahrenheit is 2.31 feet of elevation per pound-per-square-inch water pressure. Dividing the 100 feet of elevation by 2.31 feet per psi yields a head loss of 43.29 psi.
