: Hi Gary,
: RE:We water treatment guys use flow controls when needed, not undersized tubing and for a solution feeder, there is no need to control the flow.
: Many times rather then go for a mechanical device like "flow control devices" we can do it math mathematically.
: For example if a filter has a rating of no more then 20 GPM to remove sediment all one would have to do is find the in coming pressure.
: Lets assume that the available pressure is 65 PSI and we are running 3/4 lines, the volume flowing would hover around 39.37 GPM thus rendering the filter useless.
: Now if the installer used 1/2" prior to going into this filter the VOLUME flowing through this piping would be 17.5 GPM still well with in the filters capacity to remove sediment without causing undo turbulence.
: This is especially true on acid crock systems, like a floor drain in a battery room or in a laboratory where this acidic waste has to be controlled prior to entering the neutralizing tank.
: Too fast and the marble chips will not have time to do their job and not every installation has room to have a holding tank.
: Thus we have to depend on piping sized to reduce volume rather then figuring baffles or mechanical devices that are prone to failure
: Older heating steam and hydronics depended on piping being increased or decreased depending on what the condition needed.
: Hey its just another train of thought
Hey Sylvan, your confusing folks with facts and giving techs a bad name.
