Volume of water in a pipe
Could someone please help me with this question:
How many gallons of water are in a 6 inch pipe, that has 2 inches of water in the bottom of the pipe. The pipe is 500 feet long. Thanks

Re: Volume of water in a pipe
Try this page here:
http://www.onlineconversion.com/obje...nk_partial.htm You will have to convert all the base units to the same, such as feet. 6 inches = 0.5 feet 2 inches = 0.1667 feet The volume is returned in cubic feet, which you have to convert to gallons. 28.6 cubic feet 28.6 cubic foot = 213.942 857 14 gallon [US, liquid] So about 214 gallons

Re: Volume of water in a pipe
Thanks for your response, but I can,t figure out how you came up with the 28.6 cubic feet.

Re: Volume of water in a pipe
Its a bit complex, which makes it much more suited for a computer script to calculate, but its like this:
if h < r volume = (lrČ / 2) * (2 * acos((r  h)/r)  sin(2 * acos((r  h)/r))) if h = r volume = (PI * lrČ) / 2; if h > r volume = PI * lrČ  (lrČ/ 2) * (2 * acos(((r  (2r  h))/r)) sin(2 * acos(((r  (2r  h))/r)))) if h = d volume = PI * lrČ; where l = length, r = radius, h = height, d = diameter
