How much water does a pipe 6 inch diameter x 50 foot contain?

Answer 1

volume can be found by the folowing equation. 3.14 (pi) x 9 (radius squared, half diameter) x 50. which give your the volume in feet squared. after some hard calculations, that comes out to about 61 galloons. (61.1204479 galloons to be exact) your welcome. Is it 3.14 (pi) x 9" (R/2) x 600 inches (") =16956 cu.in , divided by 231cu.in (amount of cu.inches in a gallon of H2o) which = 73.4 gallon?

The answer to this question is dependent upon the material type and wall thickness of the pipe that you are referencing. 6 inch steel pipe with .250" wall thickness has an outside diameter of 6.625 inches and an inside diameter of 6.125 inches with a water capacity of 1.5306 gallons per foot of pipe or 76.53 gallons in a 50 foot long section. 6 inch schedule 160 steel pipe has .719" wall thickness but has the same outside diameter of 6.625 inches. The inside diameter of this is 5.187 inches with a water capacity of 1.0987 gallons per foot of pipe or 54.94 gallons in a 50 foot long section. Quite a difference in total capacity for two different pieces of 6" pipe.
