Minimum diameter of a circle to fit other circles inside

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).
