There is 1.5 gallons per foot in 6" pipe and 2.59 gallons in 8" pipe, so I would think there should be about 2 gallons per foot in 7" pipe.
bob... 1.998 gallon Pi x R Sq x L (12") divided by 231 as there are 231 " in a gallon
(pie)2.14R^2 * L / 27 all must be in the same units (ft. is best)
you get a (cu ft) answer h20 is 7.5 gal per cu ft 7.48 gal per cubic foot which equils 1 fixture unit If your figuring inches you take Pi x R 2 x L divided by 231 as there are 231" in a gallon IF your figuring feet you take Pi x R sq x L x 7.48 as there are 7.48 gallon in a CUBIC foot
