You can't put lbs. in a 3.78 liter jug. You have to use kilos....

Ok, George, got it. Yer right. I get:

Tank A = 17.99391 lbs/in @ a given weight of 12 lb/gal.

B = 27.58251

I'm embarassed. My dad is 92, never went past the 8th grade, and can do this in his head.

See what you have done. If you just remebered the old saying "ask ten beekeepers a question, and get eleven answers", then this could of all been avoided. You didn't have to go all out and ask some high tootin numbers question to prove that. The tanks either got honey in it or it don't.

How about marking the tank inside in inches, and letting some out till you removed an inch of honey? Then weigh the honey. You dont need no fancy shiny computors and calcubeelators for that. Just ten beekeepers telling you how to mark the tank and what to measure the container with. For that, please see the post about "scales" as there seems to be a good many beekeepers with too much time on thier hands over on that thread.

at the risk of going farther down this bad road...

height of the tanks is irrelvent for the answer he is seeking.

its simply (assuming 12lb/gal):

pi*(21/2)^2*(12/231) = 17.993 lb/in for tank A

pi*(26/2)^2*(12/231) = 27.581 lb/in for tank B

note: 231 cubic inches/1 gal

Bjornbee spake thusly:

Thanks Bjornbee for filling in, I'm home from work now, I'll take over here so you can get back to work!

Good suggestion btw, draining out an inch of honey and weighing it.. I thought of that, but couldn't find a tank the right size.

Reminds me of a story I heard once about Thomas Edison. Apparently he had asked one of his assistants what the volume of one of his light bulbs was. The assistant went off to work the problem with some complicated curve fitting techniques, triple integrals and the like. After a while, Edison became enraged at how long it was taking. He grabbed the bulb, pulled off the base, filled it with water, poured it in a beaker and measured the volume -- then sent his assistant home for the rest of the day.

I'd have sent Edison home for wrecking a bulb. He could have filled a beaker plumb full, stuck in the bulb, pulled it back out, and measured how much water was gone [img]smile.gif[/img]

Best,

TRC - you are including the volume of the glass itself into your measurement. Obviously eddison only wanted the internal volume.

he put the hight of the tanks in the opening question but that was something that can be ommited but what he wants to now is how much a inch deepness in each tank holds. thats elementry to figure out.

Just guessing here but I think maybe he wants to know what it will take to support the tanks. How strong will the legs need to be and how many will be needed? What? You put your pencils away?

How high off the ground is the tank? What is the temperature in the room? Are we at sea-level or do we need to compensate for air pressure? Are the lights on or off in the room? There are so many unknowns in all of this...

If we don't know the temperature of the room or the material that the tanks are made out of, how can we take into consideration the change in volume due to the coefficient of expansion of the material?
