Table 3 Friction Losses Through Pipe Fittings in Terms

15 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.
