a question for the pros and for the experienced and thoughtful amateurs:
this will affect my choice of pipe and tube and circ sizing and efforts to keep the wire to water side of the efficiency equations
I get it that a basic part of the recipe of hydronics is that for residential applications, you normally never want water moving at less than 2 feet per second (to avoid entrapped bubbles) or more than 4 feet per second (to avoid noise from flows).
There's also apparently a higher upper FPS limit for commercial and industrial applications, that allows for and ignores worries noise but which still sets an upper FPS limit that you have to stay under in order to avoid erosion of pipes and fittings.
that second "noise be darned" FPS figure, that's the threshold that one has to stay under to avoid erosion, seems shrouded in mystery.
what is that upper FPS limit to avoid fitting erosion?
thanks!
