How much water would be in a 480 foot one inch inside diameter pipe??  In imperial gallons please.  thanking you in advance for your help in this matter.  


Hi Marlean,

The volume of water in a pipe is

r2 h

where r is the radius and h is the length, both in the same units. I am going to use inches. is approximately 3.14 so I get

3.14 1/2)2 480 12 = 4523.89 cubic inches

One imperial gallon is 277.42 cubic inches so this is

 4523.89/277.42 = 16.3 gallons
