pie X r

pi x d = circumference

so therefore diameter from circumference = circumference/pi

you do realise flexible pipe is terrible for fluid flow don't you, assuming it's the non smooth bore variety.

what's pi x r then?

thats because i was going to put squared, and then remembered thats area

I did wonder if it needed clarifying
