Irrigation Association Friction Loss Charts 2008 Tables are based upon the following Hazen-Williams Equation: H f = (0.2083)(100/C) 1.852 (Q 1.852 /D 4.866) The result is multiplied by 0.433 to give psi loss for 100 feet of pipe.
Prior to the availability of personal computers the Hazen-Williams formula was very popular with engineers because of the relatively simple calculations required.
1 Module 3c: Flow in Pipes Hazen-Williams Equation Robert Pitt University of Alabama And Shirley Clark Penn State -Harrisburg Hazen-Williams Equation •Based on experimental work •Used to calculated velocity in a pipe based on the relative roughness and slope of the energy line Where V ...
Aconvenient form of the Hazen-Williams equation is: H L =1,000 V 1.852 0.115C(d) 0.63 CF actor For a pipe to have satisfactory flow characteristics, it initially must provide a high Hazen-Williams flow coefficient "C factor" and must be able to maintain a high flow coefficient through years of service.
