Pipe size and flow rate must be ‘matched’ to this energy using the following steps: • the elevation drop or elevation head is measured • a flow rate is chosen (refer to Factsheet #590.304-1 in this Handbook series) • the ‘end-of-pipe’ pressure is chosen (refer also to Factsheet #590-304-1)

Chart 2 provides the friction value for several pipe sizes. If the friction is high then we may want to consider a bigger pipe. Let’s do an example, say we have a flow rate of 6 gpm and we are using a 0.75” diameter pipe or tube. Then the velocity will be 4.5 ft/s and the friction 18 ft per 100 ft of pipe.

Velocity concerns—the speed at which the water is moving inside the pipe can create noise problems and, in extreme conditions, erosion problems. 2. The required head loss can become so excessive
