How To Determine - Cylindrical Tank Volume
Using the diameter of the tank, multiply the diameter by the diameter (D x
D), and then multiply by .7854. This will equal the square area of a
circle.
Area of a cylinder:
Diameter x Diameter x .7854 (D x D x .7854)
Taking the length of the tank multiply the square area of a tank, by the
length dimension. This gives you the volume of the tank.
Volume of a cylinder:
Height x Square area of cylinder (height also = length or depth)
To determine the volume in gallons of the tank, divide the volume of a tank
by 231.
NOTE: There are 231 Cubic Inches in 1 gallon of water
Cylindrical Tank Formula:
Diameter x Diameter x .7854 x Length, 231 (D x D x .7854 x L, 231)
NOTE: When a circles diameter is equal size of a square, the area of a
circle consumes .7854 or 78-1/2% of a square. The remaining 21-1/2% is not
used in cylindrical calculations. (an 1-foot diameter circle into an 1-foot
square)
One cylindrical tank 7 x 72, for each wing will hold a total of 24
gallons.
7" x 7" x .7854 x 72" / 231 = 12 gallons
11" x 11" x .7854 x 12" / 231 = 5 gallons
