Actually, the radius of a 2" pipe isn't 1". Pipe sizes are nominal sizes
and
actual inside diameters vary as to the schedule classification of the
pipe.
2" schedule 40 pipe will have the same outside diameter, but a larger
inside
diameter than 2" schedule 80 pipe and neither one of them will measure 2".
What I'm saying here is, if you require very accurate result from your
calculation, use a ruler and actually measure the pipe diameter, or go to
