Water speeds in tubing are generally limited to 5-7 fps, as turbulence at obstructions will wear metal at these speeds and higher at accelerated rates. 2 fps is required to carry bubbles downward pipes. Speeds below 1 fps can create laminar flow in water heat exchangers and limit heat transfer. Not much magic – just experimental findings.
