Rectangular Tank. Please enter the data for length, width & side water depth. Volume = Area × Length Why calculate area first? Calculate the volume your vertical round, horizontal round or rectangular storage tank can hold. We can draw squares on a real tank and see if the area matches the real world, or just think how the area compares to a full circle. So, a fish tank that is 40.64 cm long, 25.4 cm wide, and 20.32 tall has a volume of 20.975 L. If the volume of the fish tank, in cubic centimeters, is 20,975, to find the volume in liters, calculate , ÷, =. The formula turns out to be The full volume would be the same for both, but if the tank is 1/3, 1/4, 1/5 full....the formula I gave you can be used for figuring partial volumes for a vertical spherical ended (a circle) tank. Tank Shape: Rectangle Cube Hexagon Octagon Flat Back Hexagon Cylinder Half Cylinder Corner Cylinder Elliptical Corner Pentagon L-Shaped Corner Prism Volume of a Round Tank or Clarifier. The first of these refers to the following for the volume of a partially filled ellipsoid: Variable Volumes in an Oblate Spheroid. volume of the liqu id that part ially fills the tank, you should indicate if the tank is in horizontal or vertical position. All volume equations give fluid volumes in cubic units from tank dimensions in consistent linear units. Formula: 3.1417 x R² x D = Cubic Feet **** Cubic ft x 7.47 = Gallons. 3 and 4 show vertical tank variables. A rectangular tank is a generalized form of a cube, where the sides can have varied lengths. tank size). It is bounded by six faces, three of which meet at its vertices, and all of which are perpendicular to their respective adjacent faces. All variables defining tank shapes required for tank volume calculations are defined in the “Variables and Definitions” sidebar. Volume of a Square or Rectangular Tank or Clarifier. Tank volume calculator online - calculate the capacity of a tank in gallons, litres, cubic meters, cubic feet, etc. The volume of a fluid is calculated based on the depth of fluid (h) within the tank, and the radius (r) and length (L) of the tank itself.The depth of fluid h can vary between zero (an empty tank) and the tank diameter 2×r (the full tank). Quick and easy tank volume and tank capacity calculation (a.k.a. Calculator. 1 and 2 show horizontal tank variables and Figs. Compute the volume of a fluid within a horizontal tank of a cylindrical shape. Servers as a liquid volume calculator with output in US gallons, UK gallons, BBL (US Oil), and litres. For a horizontal tank with ellipsoidal ends (a generalization of hemispheres), see: Volume of a Horizontal Cylindrical Tank with Elliptic Heads Volume of a Rounded Horizontal Tank. Tank capacity calculator for on oil tank, water tank, etc. Please enter data for Tank Radius (radius is 1/2 of diameter) and side water depth. If the tank is placed uprig ht, t he volume of the liquid i n the Vessel Volume & Level Calculation Estimates Volume filled in a Vessel with Ellipsoidal (2:1 Elliptical), Spherical (Hemispherical), Torispherical (ASME F&D, Standard F&D, 80:10 F&D) and Flat heads. Graphically, Figs. So we can check to see if it is a sensible value! Aquarium Water Volume Calculator Choose the tank shape that closely resembles the shape of your aquarium. Enter values of radius, height filled, and length, the answer is calculated "live": Area Formula supporting 10 different tank shapes.
