http://irrigation.wsu.edu/Content/Calculators/General/Pipeline-Pressure-Loss.php WebhL is the frictional head loss due to fluid flowing at an average velocity, V, through a pipe of length, L, and diameter, D, with Moody friction factor equal to fm. The frictional head loss will be in ft for U.S. units and in m for S.I. units. g is the acceleration due to gravity. (g = 32.17 ft/sec2 = 9.81 m/s2)

WebGeneral form. Henri Pitot discovered that the velocity of a fluid was proportional to the square root of its head in the early 18th century. It takes energy to push a fluid through a pipe, and Antoine de Chézy discovered that the hydraulic head loss was proportional to the velocity squared. Consequently, the Chézy formula relates hydraulic slope S (head loss … WebFeet of head loss values are subject to the following conditions: a) Pipes carrying clear water at approximately 60° F (15.6° C). b) Pipes are flowing full. c) Velocities of water are generally less than 10 feet per second. Note: HDPE is commonly sized by outside diameter. If in doubt, use the next smaller pipe size. Page 2 citation for a website generator
