How many gallons of water is in 10 foot of 1.25 copper pipe?
Figure it out. It sounds like copper tubing so the OD is 1.25, the ID is around 1.15 inches so: (pi/4) * (1.15 inches)^2 * (120 * inches) * (1 gallon / 231 inches^3) 0.54 gallons
If the Inner diameter of the pipe is 1.25 then the correct formula to determine the volume of a cylinder would be: pi*r^2*h where r is the radius and h is the height radius 1/2 diameter 1.25/2 .625 r^2 .625*.625 .3906 multiply by pi to get the area of the top of the cylinder ** 1.227 square inches *** to get square feet you divide by 144 (12 inches in height and width) 1.227/144 .00852 square feet h 10 feet .00852 square feet * 10 feet .0852 cubic feet 1 cubic foot 7.481 gallons 7.481*.0852 .6374 gallons If the tube is 1.25 Outer Diameter the wall thickness is about .065 which gives an ID of 1.12 (you have to subtract 2 times the wall thickness) substitute 1.12 for the 1.25 in the above example and you get .5117 gallons
is it 1.25 diameter copper pipe?please clarify
