How to figure size for 10 gallon tank

admin

I was asked by a friend to fabricate a rectangular hydraulic fluid tank that can hold approx 10 gallons of non-pressurized hydraulic fluid. He bought an old hydraulic press that is missing the tank and other parts. Because the press appears to be relatively small I believe a 10 gallon tank is overkill, but it is his money. Anyways, is there a way to figure out what the approx measurements (size) would be if a person wanted this tank to be approx 36" long..........thanksLast edited by Pat; 03-29-2004 at 08:05 AM.
Reply:35 7/8" Length11" wide6" deepThis will be real close to 10 gallons.
Reply:Thanks a million Jim,That is just what I needed.
Reply:The formula to get volume is  gallons X  0.1337= cubic feet. Be sure to add about 5% extra for expansion of you hydraulic fluid during those "hot" Texas summers.
Reply:Length x Width x Height = Volume in cubic inches1 gallon (US Liquid) = 231 cubic inches, so 10 gallons = 10 x 231 or 2,310 cubic inches36 inches x Width in inches x Height in Inches = 2,310 cubic InchesNow, you can determine which measurement, Width or Height, can’t vary too much in inches because of the tank’s physical location.  Let’s say you feel the Width of the tank can’t be more than one foot, or 12 inches, then:36 inches x 12 inches x Height = 2,310(36x12) x Height = 2,310Height = 2,310 / (36 x 12)Height =  2,310 / 432Height = 5.35 inches  Check:  36 x 12 x 5.35 = 2,310 cubic inches So how much is .35 inches?  I hate this part.  Lets do it in sixteenths.  .35 x 16 = 5.6 sixteenths, or say 6 sixteenths6/16 = 3/8 inches  5 3/8 inches = Height----OR---- What if Height was a problem, and the Height could not be more than say 8 inchesSame as above, only you solve for Width36 x Width x 8 = 2,310Width = 2,310 / (36 x 8) Width = 2,310 / 288Width = 8.02 inches or close enough to 8 inches.Check:  36 x 8.02 x 8 = 2,309.76 or close enough to 2, 310Regards,Bill Vorhies
Reply:Jim...Can those of us in the Northern climates deduct 5% .....thanksMasonvalley.....Could you expound on this just a little bit........ha ha, just kidding. I am glad there are people on this board that payed attention during math class.........thank you.
Reply:OOPS! I looked at the wrong post for location.  But do  allow about 5% for expansion even up north. If the fluid gets warm it will expand.
