It should be
(((pi r***2) * 12)/231) ...... because 231 ci is a gallon

a 2 inch pipe has a r of 1 and 1 squared is 1
(12 * pi) / 231 is .163 gallons

for a 4 inch pipe
2 squared is 4 so
(4 pi * 12)/231 = .653 gallons per foot of pipe

I always seem to mess up math so maybe someone would like
verify this.

OK, before you flame me for this question...I admit I am lazy and should
be
able to come with this myself, but I am lazy, so I'll ask here first,
because I am lazy. Did I mention I am lazy?

Does anyone know the volume for, or the equation for calculating the
volume
of a pipe per foot of pipe? IE, one foot section of 2'' pipe holds x
number
of gallons of water. I want to calculate this for various size pipes.
