WebSo, if you're using the Hazen Williams method, you would want to use a multipler less than 1 in order to increase roughness (smaller H-W C = more headloss). However, a multiplier of 90% doesn't necessarily mean 10% more headloss, so … http://www.sd-w.com/channel_flow/head_loss/

Pipe Friction Loss Calculations

WebThe Hazen-Williams equation is commonly used for water distribution systems, where the flow of water is typically in a closed system under pressure. The equation is particularly useful for predicting the flow rate in existing systems where the pipe roughness is not well known or cannot be easily measured. View the full answer. Web(for Hazen-Williams) Q l = Flow through pipe “l” (m 3/s) N = Number of loops n = Value based on which head-loss equation used (i.e. 1.852 for Hazen-Williams) Equation 1 is essentially the sum of the head-loss in a predefined direction around a closed loop. Once the loop equation has been determined, the WebSpecified Data l = length of pipe (ft) 100 c = Hazen-Williams roughness constant 130 q = volume flow (gal/min) 23 dh = inside or hydraulic diameter (inches) 1.5 Calculated Pressure Loss f = friction head loss in feet of water per 100 feet of pipe (ft H20 per 100 ft pipe) 5.93 f = friction head loss in psi of water per 100 feet of pipe (psi per ... inbuilt induction
