Energy efficiency in piping design

Tags


There are simple but major opportunities to save energy through improved piping design. For instance, as in this case (a main pump with an identical in-place spare pump—or analogously for two parallel pumps), pipes are often laid out at right angles rather than in a geometry that minimizes friction and cost. In general, fat, short, and straight pipes have enormously less friction than thin, long, and crooked pipes. (Friction falls as nearly the fifth power of pipe diameter.) In addition, energy losses compound quickly when fluid must pass through unnecessary fittings or valves.
