Volume of a barrel.

[ggauny@live.fr]

In my prime younght, in my grand'mother little farm in Ancemont village of Meuse, when she bought a barrel she ask me to verify the capacity. In this time I simply fill
the barrel with a water-pump and his counter in litres, décilitres and centilitres. When barrel is full, I see the counter and I say to grand'mother. She was very
suspicious wary and this method say if the dealer is a liar on capacity of the barrel (to have more money) and second this method say if the barrel is water-proof : very important you know.
It is not "mathematic" but very effective !!!!! only with not bigs barrels of course.

I will not write this on my copy for the professeur....
