kind of a math Q about air pumps
    #3671618 - 01/24/05 10:46 AM (11 years, 10 months ago)

alright, i have a 20 gallon air pump that i'd like to put in my 50 gallon tub where my casings will be going, just wondering how many times a day a 20 gallon pump will circulate fresh air in it? or the Q could be possed as, how quickly will a 20 gal pump fill a 50 gallon tub? know what i mean? thanks!

>hats the flow rate or output rate of your pump?

loo, why do you think it is called a "20 gallon air pump"?

It can mean 2 things:

Either it moves 20 gallons per hour, or it is suitable for a 20 gallons aquarium.

In the later case, it should output roughly the double or a little more of the aquarium volume per hour, so ~50 gallons per hour.

get a trashbag or something labelled 20 gallon or 50 or whatever.
tape the outlet hose of your waterpump to that bag and switch it on,
measure the time till its blown up and voila youll have your throughput ...

think?
peace ohm :mushroom2:

thanks all, i was guessing 20 gal/hour but wanted to make sure cause i didn't see any indications on the box or manual. Would u think a 10 gal pump would supply enough fresh air to 2 casings inside a closed 50 gal tub per day? i have both a 10 and 20 gal pump available. thx again

Most pumps usually have a CC rate... EG, my pump is a 5500 = 5500cc an hour.

If you GOOGLE "5500cc to gallons" you get...
"5500 cc = 1.45294628 US gallons"
So... 1.45294628gph * 24h = 34.8707107gpd.
(Gallons Per. Hour * Hours = Gallons Per. Day)

Fill your sink with water. Submerge a quart jar or 2 liter bottle. Turn it upside down with the opening still under water. You can pull it most of the way out now and the water will stay in.

Stick your air hose in the mouth of the jar. Time how long it takes the jar to fill with air.

Flow rate will be reduced somewhat if you are pushing the air through bubble wands etc.
