Help with measuring tank

Hi, please help :)

I have 2 x 24000 litre tanks, and I need to measure the quantity of diesel inside.

The tanks are cylyndrical, and lying horizontally.

The distance from the bottom of the tank to the hatch at the top is 2260mm [edit: that would be the inside diameter, just to be clear]. Now, I need to make a dipstick that has 500 litre increments to measure the liquid inside.

Please tell me exactly where I must put the gradations on my dipstick.

would this help ?

Thanx kco, couldn't find a metric one, only inches and gallons, this helps a lot

no worries, good luck with the measuring and let us know how it go.

UGH!

Now it comes up with this:

I need the liters in round figures, not the mm. Example, I need depth for 500 l, 1000 l, 1500l........ 23500l, 24000l

anybody have any ideas?

the only way I could think of, it cheating though ,is by pouring in 500 l in a time marking it off till half way (is the same for the top half).

geez, thanx.

I've been looking in excel if there's no function that could calculate the mm if I input the litres, but all those things seem to be linear, and this clearly is not.

btw how long is the tank ?

6m long, 2,26m inside diameter.

24069 litre capacity

The trial and error idea might be a bit tedious to do - but you'll be pretty certain that your dipstick is properly graduated by that method.  Maths might need an act of faith in the end.

I'm not doing the work, as I've forgotten it all, but I'm almost positive this is like a 2nd semester Calculus Integral problem. Start asking someone sharp w/Calculus.

Oh, and hopefully obviously, halfway on the stick is 12000, w/the gradations closer together on either side of that point, and further aprt towards the ends.

by using the link I gave you, you can be able calculate the depth when you want the volume to be for example for every 500 l. Type in the depth where you want the volume so ....

so far I got.....

121mm - 498 l

194mm - 1000.8 l

256mm - 1503.7 l

312mm - 2006.9 l

363         2499.7 l

412         3000.4 l

459         3503.1 l

504         4002.7 l

547         4495.3 l

590         5001.2

632         5507.1

672         5998.5

712         6498.5 

752         7006.1

790         7494.6

829         8001.7

867         8500.7

905         9003.8

942         9497.0

980         10,006.5

1017        10,504.8

1054        11,004.7

1091         11,505.8

1128          11.993.8 

half way  1130     12,034.5

1165           12,509

Ah, ok, i see what you're doing, kco, cool idea

do you want the rest of it ? I got up to half way so far....

The tank has 24000lt, divide that for 500lt You get 48 parts. Take the 2260mm total height and divide for 48 and you get 47.08mm for each 500lts.

I'm right?

no, unfortunately not. see post #13

No.

lol, kco, i'll have to put you on the payroll
