This is perhaps no so simple as it looks. Original program probably include calculations of partial volume of heads of the vessel. Calculating heads' volume can be not so simple as they can be of different shapes, for example spherical, conical etc. As far as I found in the internet calculations of heads' volume in most cases are estimated, the code for it being much longer than for simple cylinder body. On the other hand volume of heads is important as they have significant percentage of the whole volume.
It should be said here as well that body of the vessel can have different cross-sections, not only circular, but elyptical for example.
If the original program takes account af all this it certainly must be complicated

Here they take in account also the different shape of the heads, unfortunately not a case of sloped vessels..
This can help of course, but is not actually what we are looking for, cause it is a "on-line" calculation.

By the way I don't understand very well the graphical rapresentation on the right
