How do I work out the fluid capacity of an oil drum?

I have measured the height and I have the radius of the top, how can I establish how many litres it'll hold?How do I work out the fluid capacity of an oil drum?
it is written on the labelHow do I work out the fluid capacity of an oil drum?
Assume radius of base = r cm and height = h cm


Volume = 露 r虏 h cm鲁 = 露 r虏 h / 1000 litres
V= (h)(pi)(r^2)





Then convert units^3 to liters
Same as any 3d shape. Measure the surface area of the top (蟺r虏) and multiply by the height. Assuming all your measurements are in decimetres, that'll give you your answer (a litre is a cubic decimetre).
I agree with the answer already provided by ';Ignoramus'; which states the following:-


';Barrel volume will be the surface area of the top times its height.


So V = Pi x R^2 x H


This will give the volume in cubic units. So it is better to convert to metric in the first place.


One inch = 2.54 cm


Once you have the volume in cubic centimeters (cc), then you can divide by 1000 to change this to liters. (1000 cc to one liter)
Not wanting to be pedantic; all the previous formulaes are correct however make sure your measurements are the internal drum measurements.
Length x Width x Depth





Then to get the volume in gallons you will have to divide by 269





Also...





R^2 * Pi * H / 1728 = Volume





Hope that helps!

Volume in liters will be pi times height times the square of the radius, all measured in decimeters.
fluid capacity is the same as volume.


look up the formula for volume of a cylinder and apply it.


remember that the real volume probably holds more than


the barrel holds in practice because you do not fill a container


of almost any kind up all the way to allow for heat and impacts


and opening and closing.
V = h*(pi*r^2)





take the area of the top (pi*r^2) and multiply it by the height to get total volume in units^3. You will have to convert then. 1 cm^3 = 1mL
pie r squared
