drain hole size
drain hole size
(OP)
Hello all
one of our products maintains a water level of 1/2" when not in use. Looking at adding a slow type of drain hole(about 1/8" dia) in aluminum that will always be "peeing" while in use but will allow the remaining water to drain when not. Wondering if anyone has any knowledge of hole shape/size/dia data so this low head height water will drain without just covering over the hole due to surface tension of the water. Maybe the hole should be tapered? maybe a radius on the top edge? Trying to get a feel for any applications out there before testing....

a micron filter we use upstream should negate this some but its still a concern..I agree.
Our options here are limited.

I'll have to ponder the drain line with a float...
Am testing different shapes of small drain holes this week.
