Thanks for the replies.
Russ - I'm not looking for the effect on flow rate, I'm looking the actual flow rate - a number, specifically in GPM and preferably within 5% +/-
Q_goest - Basically, I have a 3" pipe that enters the heat exchanging portion of a packaged A/C unit. The water flows...
Is it possible to calculate the flow rate of water through a restrictionless device (a tank, for example) if you know the inlet & outlet diameters and pressures?
I've been looking all over, but all I can seem to find is formulas for pressure drop in a length of pipe...
Thanks!
