Help a Lazy Ponder Out?
OK, before you flame me for this question...I admit I am lazy and should be
able to come with this myself, but I am lazy, so I'll ask here first, because I am lazy. Did I mention I am lazy? Does anyone know the volume for, or the equation for calculating the volume of a pipe per foot of pipe? IE, one foot section of 2'' pipe holds x number of gallons of water. I want to calculate this for various size pipes. -- BenignVanilla tibetanbeefgarden.com x-no-archive: yes Remove MY SPLEEN to email me. |

It should be
(((pi r***2) * 12)/231) ...... because 231 ci is a gallon a 2 inch pipe has a r of 1 and 1 squared is 1 (12 * pi) / 231 is .163 gallons for a 4 inch pipe 2 squared is 4 so (4 pi * 12)/231 = .653 gallons per foot of pipe I always seem to mess up math so maybe someone would like verify this.

Actually, the radius of a 2" pipe isn't 1". Pipe sizes are nominal sizes and
actual inside diameters vary as to the schedule classification of the pipe. 2" schedule 40 pipe will have the same outside diameter, but a larger inside diameter than 2" schedule 80 pipe and neither one of them will measure 2". What I'm saying here is, if you require very accurate result from your calculation, use a ruler and actually measure the pipe diameter, or go to http://www.gotspud.com/howto/pvc.htm Paul "Howard" (remove XYZ) wrote in message ...

I want to calculate this for various size pipes. Here is a web page that has a chart of the amounts of water per foot. http://www.thermidaire.on.ca/charts/pgw.html Haven't gone to the web page but the formula is rather easy. All measurements must be in ft (i.e. 1 inch is 1/12 ft). Then the volume of the pipe (a cylinder) is given by the formula V = pi(3.14) X radius squared. Radius is 1/2 diameter. This gives the volume in cubic feet of water. To convert to gal multiply by 7.5. So for a 2 inch diameter pipe (radius = 1 inch) one foot long. Volume (in gal) = (1/12)sq X 3.14 X 1 ft X 7.5 In this example this equals 0.16 gal. Another example: Volume in gal of a pipe 10 ft long and 10 inches in diameter V = (5/12)squared X 3.14 X 10 X 7.5 = 41 gal Should you ever need the weight of the water (in lbs) in the pipe, just multiply the volume in gal by 8.33. This is probably more than you wanted to know. Bill -- Bill and Nancy Weiler Tony, Wisconsin http://home.centurytel.net/spinandfish/spinandfish |
