A Math Question

I need to know how to figure How many gallons of liquid are in a piece of 6 inch pipe 50 ft long

Can any one tell me how to figure this up or just tell me the gallons

Thanks in advance

Bill

One U.S. gallon is 231 cubic inches
A 6" pipe has a radius of 3"
Length 50' x 12 = 600 inches
The volume of a cylinder is  V=nr2h
R is the radius and H is the height (length)
The volume in your pipe is:

V = n32 x 600 = 

68.37 gallons

It's closer to 73 1/2 gallons Bill.

V= Pi * (r^2*L)  or

3.1416 x 5400 (converted to inches) =  16964.64 / 231 (cubic inches in a gallon) = 73.44

I get 73.44 gallons.

pi X radius² X height  = volume

3.14159 X 3 in.² X 600 in. = 16964.6 cubic inches

16964.6 in.³ / 231 in.³ per gallon = 73.44 gallons

Edit: Looks like Al got here first with the same answer.

That's why i put one of these " " by my answer. Math ain't one of my best subjects.

I got 73.4398


Edit:  Looks y'all beat me to it.

Leave it to the plumber to throw that in there?

When you figure out the actual inside diameter of the pipe, go here

Plug in the numbers and divide the result by 231

Thanks guys
this was not a math test I was trying to figure out how many gallons of water in my water well

The well casing measurews 6 inches across  ID inside diameter

bnccont ,
If the well is dry, the amount of water in the well pipe is exactly zero.  :roflmao:

Rich I am so happy you got that figured out  :roflmao:

Ok So here is the story

I am trying to keep from putting a 275 gal storage tank for water in the basement.The well is 160 ft deep
the water comes in at 130 ft the pump is set at 158 ft there is at least 50 ft of water in the well so that puts the
water 20 ft above where it comes in.I am not sure how many gals per minutes this well makes.The way I got it figured is if it can push the water up the pipe 20 ft higher then where it comes in it should be a pretty strong well.
I replaced the submersible water pump today to see if I can keep water in the 2 houses that are drawing off of it.
The pump I pulled out had the screen pretty much plugged up,so I figured the pump was getting hot due to the lack of water it was able to push.Now that the new pump is installed and water running we seem to have better water pressure and alot better volume.I hope this has cured the problem
Thanks for all your input
