a 6 inch copper pipe that is 50 ft long, how many gallons would be in the pipe?
73.4 gallon Area of the 6 inch pipe is 28.26 inch pipe is 600 inch long 231 cubic inch in gallon
Don't forget that pipes are sized to the outside diameter so that the inner (water holding) diameter is less by twice the thickness of the pipe wall. Anyone care to guess why?
