Hi Is there a formula to work out the minimum diameter of a circle to fit a range of smaller circles inside it? I.e I have a pipeline which needs to be big enough (i.e have an internal diameter) to fit a varied range of smaller pipes inside it. e.g sometimes the pipe may need to house: 2 x 100mm pipes inside it or 2 x 100mm & 4 x 200mm etc.. I'd be grateful for the help. Thank you.

I doubt that any simple formula exists for that. For practical reasons, the interior pipes need some freedom of movement (especially if all the pipes are flexible).
