Nitro Junkie February 10, 2008 Share February 10, 2008 I finally got my RO/DI setup and had a question about how to figure the water volume at certain depths in the can short of dumping in 5 gallons at a time and marking the depth. Has anyone else already figure this out and save me some time ? Link to comment Share on other sites More sharing options...
Boret February 10, 2008 Share February 10, 2008 I finally got my RO/DI setup and had a question about how to figure the water volume at certain depths in the can short of dumping in 5 gallons at a time and marking the depth. Has anyone else already figure this out and save me some time ? Use this calculator to find out the volume in cubic inches. It takes only 2 measurements, radius (just measure from side to side and divide by 2) and height. This will give you cubic inches, you take that number and divide it by 231 (1 gl = 231 cu. in.) and you get the gallons. My RODI holding container has a Radius of 9 inches. So every 4.6 inches of height is 5 gallons. Now that is for a perfect cylinder. If your container is wider at the top then just measure by 5 inch sections, and calculate volume for different radius.

kngfisher February 12, 2008 Share February 12, 2008 only problem is that the brute cans are tapered slightly Link to comment Share on other sites More sharing options...
bigJPDC February 12, 2008 Share February 12, 2008 Awesome! I can't wait to get home and measure one of those 5gal HD Homer buckets, to see how much is really in them. And that ought to tell you something . . . Link to comment Share on other sites More sharing options...
Brian Ward February 12, 2008 Share February 12, 2008 (edited) Boret, Are you really asking people to walk the fine line between arithmetic and calculus? Calculus to find the volume of the can is only a short step from what you suggested ... Why do you need to know exact volume? I just have a selected water level, use a solo cup to measure the salt. Trial and error the first time to get the level right, but then you know it's water to the mark and 3 solo cups of salt ....

bigJPDC February 12, 2008 Share February 12, 2008 If you look at a homer bucket in the right light, you'll see that the orange stops becoming transparent up near the rim. If I fill it to that point, so I can no longer see through it, and add one solo cup of salt I get 1.025 SG every time. I like to do it one bucket at a time because the act of pouring that much water into the Brute can gives violent agitation just in case any salt hasn't dissolved.

Nitro Junkie February 12, 2008 Author Share February 12, 2008 I wanted to figure the volumes at different depths so i have a starting point to figure out the right salt mix amount Link to comment Share on other sites More sharing options...
