It's been far too long since fluids for this guy... I'm looking to roughly design a sorta long, thin nozzle/outlet, something like an air knife but with a much lower supply pressure (maybe 5~10 psi), and a really low flow rate to go with it. I figured "air flow through a narrow slit" would be pretty easy to find a plug-and-chug for, but I've not found anything yet. Am I just looking for the wrong thing, or is it so dead simple that nobody bothers to write it up, or so complicated that nobody bothers to write it up? I'm not necessarily looking for a 3 decimal precision result, more like an order-of-magnitude starting point for an adjustable type design before I go digging through the attic for my old textbook...
