The best practice is a flow velocity of 3 ft./sec. or less. Flow rates up to 5 ft./sec. are possible for power generation. Flow rates over 5 ft./sec. are problematic and not a wise design criteria. The chart is for cast iron and thicker grades of pipe. Thinner or lower classes of pipe will be slower.
