WebTable 6-3 indicates that values of the entrance loss coefficient range from 0.2 to about 0.9 for pipe-arch and pipe culverts. As shown in Table 6-4, entrance losses can vary from about 0.2 to about 0.7 times the velocity head for box culverts. For a sharpedged culvert entrance with no rounding, 0.5 is recommended. WebFriction Loss Through Pipe The Hazen-Williams equation below is widely used to calculate friction loss for water through PVC and CPVC pipe f = .2083 x (100)1.852 x G1.852 C di4.8655 Where: f = friction head of feet of water per 100' for the specific pipe size and I.D.
