http://www.moyno.com/dmdocuments/shcps_article.pdf Web15 Year Old Pipe - The friction values for Old Pipe are based on Williams and Hazen coefﬁ cient of C=100. Values for 3 inch and larger sizes are for cast iron pipe; smaller sizes refer to steel pipe. For existing older type installations, these higher values are generally used for estimating friction losses.

Webdepending on the pipe type, pipe size and the water velocity. The imperial form of the Hazen-Williams formula is: hf = 0.002083 L (100/C)1.85 x (gpm1.85/d4.8655) where: hf = head loss in feet of water L = length of pipe in feet C = friction coefficient gpm = gallons per minute (USA gallons not imperial gallons) Webthough we assumed otherwise in Example 1). If the Hazen-Williams (H-W) equation is used, the friction intensity factor is CHW, which is assumed to be known for a given pipe. To demonstrate how we can identify the characteristics of an equivalent pipe for a given real pipe network, we consider again the system analyzed in Example 1.
