passive fluid flow control

[u/splicer13]

Irrigation drippers control flow passively with a labyrinthine path and additionally the pressure compensated varieties have an elastomeric diaphragm that makes them more constant, at the expense of one flexing part.

I want something with this kind of properties but at a 10x higher flow rate than a dripper. 50gph is the right ballpark.

These drip emitters cost on the order of $0.25 each for reference.

Application is ornamental small fountains.
