Basically I need the inside diameter of 8' of pipe that will hold 5 gallons of water. Can anyone help?

According to this table you'll need a 4" pipe 8' long. http://www.engineeringtoolbox.com/pipe-water-content-volume-weight-d_1734.html
I come up with 91.95" of 4"id pipe to hold 5 gallons.
Area of pipe is πr2= π x 2 x 2 = 12.56 sq inches. so 1" of 4" id pipe - 12.56 cubic inches.
1 Gallon = 231 cubic inches, so 231 / 12.56 = 18.39" of pipe for each gal.
18.39" x 5 gal = 91.95" of pipe needed.
or, conversely:
231 cu in per gal x 5 = 1155 cu inches for 5 gals.
1155 divided by 8' (96") = 12.03 cu inches per 1" length.
12.03 divided by π - 3.82 inches which is the radius squared.
square root of 3.82 is 1.957" radius, x 2 for diameter = 3.914" diameter pipe or about 3 15/16.
Go

1. 5 gallons of water = 1155 cu in.
2. Change the inside diameter (d = 2 x radius) and height to equal 1155 cu in. Your choice for whatever is available to get it done. See the calculator section.
4" id pipe x 96" l = 1206 cu in.

Thanks everyone - Its looking like 8' of 4" pvc pipe will get me real close. I really appreciate the responses 
close is good enough... I'm just making a PVC pipe nipple waterer for my chickens. I may need to go with thick wall in order to be able to have enough meat to thread the nipple holes but we shall see...

Got your idea/plan for the chicken waterer. That's a slightly different beast from a vertical pipe holding 5 gallons of water.

Yeah it is... I'm going to strap it to the back wall of the coop and have it where I can fill it from outside the coop. I think all I need to be concerned with is making sure the pipe is good and level.

This may be useful food for thought as you get your plan together.

I made mine with standard schedule 40 pvc and had no problems threading the nipples. Took the chickens about 30 minutes to figure it out.
Thanks... I ordered 25 nipples its way more than I need. 25 is the same price as 10 - so I guess I'll have a bunch of spares.
