Calculate Volume of an straight pipe with non-standard X-sec

[el]

Hi,
I need to calculate the volume of water in a straight pipe (10m long), but
with an odd Xsectional shape, for each 10mm increment of water height. I'd
tried to draw the Xsection of the pipe, sliced it with lines of 10mm apart
and then found the area of each slice. It's time consuming. Are there any
better ways to do it? Any suggestion on how to do it?

Is the area of each of your cross-sections different? In other words, does the cross-sectional area of your pipe change over the length, like a long cone?

Is the section symetrical about the centre line?

If so, look at the calculation for the volume of a torus.

I use this in a lisp program to determine the weight of shafts and other
machined cylinders.

How about you make a solid to completely envelope the pipe, slice it to
match the two ends of the pipe, locally if necessary, make a copy of the
pipe onto itself and subtract it from the new solid, then 'seperate' the
(hopefully) two parts of the solid to leave a solid which matches the
internal space of the pipe and then use Massprop to give you the volume.
