Hi,

I'll be somewhat surprised if it is totally impossible. Every dimension/quantity needed is I believe known, and I suspect the answer involves calculus. My thoughts in support of this are along the following lines.

Think of each section in it's own right. From e^(i*pi) 's response to my other thread

it is possible to calculate the height from a known volume. So think of the liquid only going into the cylindrical part of the composite tank. Clearly the height can be calculated. But in reality some of this liquid goes into the end sections, thus lowering the height in the overall tank, and the volume in the cylindrical section.

Now assuming we can calculate the reduced volume in the cylindrical section we can again calculate the height. etc. to infinity.

Obviously that assumption of mine is the key and the difficult part of this process.

Regards
