The filled volume of a rectangular tank is just a shorter height with the same length and width. Total volume of a rectangular prism shaped tank is length times width times height. The filled volume of a vertical cylinder tank is just a shorter cylinder with the same radius, r, and diameter, d, but height is now the fill height or f. A = πr 2 where r is the radius which is equal to d/2. Total volume of a cylinder shaped tank is the area, A, of the circular end times the height, h. However, if the fill height f is greater than 1/2 of d then we use the segment that is created by the empty portion of the tank and subtract it from the total volume to get the filled volume V(fill) = V(tank) – V(segment). If the fill height f is less than 1/2 of d then we use the segment created from the filled height and V(fill) = V(segment). The filled volume of a horizontal cylinder tank is calculated by first finding the area, A, of a circular segment and multiplying it by the length, l.Īrea of the circular segment, the grey shaded area, is A = (1/2)r 2( θ – sin θ) where θ = 2*arccos(m/r) and θ is in radians. A = πr 2 where r is the radius which is equal to 1/2 the diameter or d/2. Total volume of a cylinder shaped tank is the area, A, of the circular end times the length, l. These calculations will give you cubic measures such as ft 3 or m 3 depending on your units of measure. Methods to calculate the volume of tanks and the volume of a liquid inside a tank. Actual water and oil tanks may not be perfect geometric shapes or might have other features not accounted for here so, these calculations should only be considered estimates. These tank shapes are calculated assuming exact geometric solid shapes such as cylinders, circles and spheres. Tank volume calculations are based on tank geometries shown below. If you are seeing no answers at all, enter a zero in the box above, which willĮliminate all formatting but at least you will see the answers.Click here to access the Tank Volume calculator (instructions listed below this link): Tank Volume Calculator Tank Volume Calculator Tank Schematic:Įstimate the total and filled volumes of tanks such as oil tanks and water tanks. Most browsers, will display the answers properly but You may change the number of significant figures displayed by Will not be in scientific notation but will still have the same precision.

The default dipstick chart increments are based on the diameter value. It would be better to input this as 15 inches and 24 inches, then clicking the "inches" button so that the default chart now has 15 lines. For example, if you are inputting information for a tank that is 1.25 feet inĭiameter and 2 feet in length, you will end up with a default dipstick chart that has two lines - zero feet and one foot.
The default dipstick chart is in increments of one but you can change that by clicking on one of the increment buttons.Īn alternative to this would be inputting a different set of units. In addition, a dipstick chart is automatically generated. If you need a vertical cylinder calculator, click here.īesides calculating volume for any particular depth, this calculator can also produce a "dipstick chart" showing volume across the entire range of tank depths.Įxample: Inputting liquid level = 3, diameter = 24, tank length = 30, then clicking "Inches" will display the total tank volume in cubic inches and US Gallons and will also show the volume at the 3 inch level. Use this calculator for computing the volume of partially-filled The numbers input above are in which units?
