Head loss check valve
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. WebTotal head loss in a pipe -. hTotal = hZ + hL + hF. Pressure drop due to head loss in pipe is calculated as. ΔP = hTotal.ρ.g. where, ρ is fluid density. There are several methods for estimating pipe fitting losses like equivalent length method, K method, 2-K (Hooper) method and 3-K (Darby) method. 3-K method is most accurate followed by 2-K ...
