Number of Holes for Spray Bar

[Jerry Baker <jerrybaker at attbi_com>]

This was discussed briefly in the past, but it was never sufficiently 
answered IMHO. There has got to be some way to calculate the number/size 
of holes in a spray bar that one can have before the flow is no longer 
equal out of all of the holes simultaneously. It is true that this is a 
hydraulic flow problem, but it is not true that you can have an 
arbitrary number of holes and still get even flow.

This is the same problem that I imagine engineers are faced with all the 
time. An example might be to figure out how many secondary water lines 
can tap into the main and keep each secondary receiving equal flow.

I don't mind researching this myself, but I do need a little help 
getting off in the right direction. I don't even know what you call this 
kind of problem, so searching is difficult.

Anyone?
