Assuming you get 100gpd out of your 100gpd RO/DI (usually you don't get the full flowrate out of those things, but let's just ignore the details for the sake of guesstimating the flowrate ) that's. . um .. 100gpd =~ 400 litres per day = 400,000 ml per 24 hours ~270 ml per minute (1440 minutes per 24 hours). Hmmm, ok, that seems a little fast.

60ml/min is basically on right on the verge of starting as a steady stream, whereas any slower it's actually perceivable as a "fast drip-drip-drip-drippety-drip."

Basically I'd just take a known volume container (measuring spoon, measuring cup, whatever), and count how long it takes to fill up to a certain level, from that you can figure out your flowrate.

ok thanks..i will do that.
