How many gallons is a barrel BBL?

[dano2840]

ive got a tank that says 25 BBL on it, it looks to be about 400-500 gals but i dont know, some one calculated it was 25 bbl based on the dimensions i think from what i can make of the pencil calculations on the side. any one know? or does any one know how to figure it out if i got the dimensions?

We need the diameter of the tank and the length if its round. Length width and height if its square. By the way a barrel is 42 gallons according to Google.

ok i will get those measurements tomarrow, thanks

a barrell in syrup is supposed to be 31.5, that would be 750 gal

[tuckermtn]

yes I was told by Bruce Bascom that a BBL is 31 gals.

A barrel of crude oil is 42 gallons and of course we all know about the 55 gallon barrel.

All syrup and sap related , a barrel is 31.5 gallons

I think a bbl of syrup is the same as a keg of beer, 31 gal, 1/2keg 15.5 etc. Use 31 gal in your calculation.

Calculation for gallons.

All measurements in feet.

Rectangular:
L x W x D x 7.48 gal/cubic foot

Round

PI x DIA^2 / 4 * D x 7.48 gal/cubic foot

Calculation for gallons.

7.48 gal/cubic foot



that is great to know. Thank you! I never knew the volume of a gallon. I mean the cubinc feet. I always had to go to a conversion website.

I guess an engineering degree is good for something...I remember all these formula's and conversions...and sometimes they're useful.

[KenWP]

Except for when your Canadain you have to figure out how many gallons it is when your gallons are bigger. Our gallons are 16o oz. When I am reading boiling rates I have to convert as 3 US gallons is 2.5 Canadain gallons or there abouts.

If you like that, check this out. I have it printed off and tacked right next to my meter.

I have a water meter on my head tank to determine how many gallons of sap I'm boiling off an hour. I used to have to make the calculation - now the chart does it for me.

but its one of those ones where its rectangular at the top and is round at the bottom, do i have to figure out circumference or some thing?

[Amber Gold]

Is it a round bottom tank? If it is, measure the depth of the rectangular portion and calculate that volume. For the round portion measure the depth from the rectangular portion to the bottom of the round portion. For ease of calculation I'd just consider a rectangle with H = to the depth you measured, B = to the width of tank. Calculate the area of the triangle using A = 1/2 x b x h and the volume which is V = A x L(of the tank) x 7.48. This will get you close enough to the area of the round portion.

That's confusing If it is round where does the rectangular portion come from?

[Amber Gold]

If it's a round bottom, isn't the upper portion above the round bottom rectangular in shape? The bottom round portion can be treated as a triangle and the result will be close enough.

Here's another tidbit...a gallon is 231 cubic inches

Amber Gold Gotcha When you said round bottom I was picturing in my head my gathering tank with a circular bottom. Like an O not a U shape. Makes sense to me now. Thanks.
