A storage tank is a container that is usually used to hold liquids and sometimes used to hold compressed gas.

Use this online rectangular tank storage capacity calculator to calculate the amount of liquid or gas that can be stored in a rectangular tank.

Use internal dimensions as much as possible to eliminate errors due to tank wall thickness. It is assumed that the fuel tank is installed on a level ground.

This tool calculates the volume of liquid held in a rectangular shaped tank using the measured level of the fluid. Where possible use internal dimensions to remove errors due to the thickness of the tank walls. It is assumed that the tank is installed on level ground.

### Tank Level & Dimensions

This calculator requires the following measurements to determine the amount of liquid in the tank.

#### Height of Liquid

Enter how high the liquid is from the bottom of the tank. If the outlet is not positioned close to the bottom of the tank then deduct the height difference in order to determine the usuable amount of fluid held in the tank.

#### Height of Tank

This the fixed measurement of the tank height. If the overflow and outlet are not positioned close to the top and bottom of the tank then subtract the height difference of each from the total tank height so that the usable capacity of the tank is factored into the percentage of fill calculation.

#### Length of Tank

Enter the length of the tank in your preferred measurement units. Ideally this should be the inside length, if the thickness of the tank wall is significant.

#### Width of Tank

Enter the width of the tank in your preferred measurement units. Ideally this should be the inside width, if the thickness of the tank wall is significant.

### Contents of Tanks

The quantity of liquid held in the tank is calculated here. If you have entered the outside dimensions of the tank and not considered the thickness of the tank walls in your measurements, the answer will be higher than the correct amount.

#### Volume of Liquid in Tank

The calculated volume of liquid derived form the fluid height entered above will show here.

#### % Full Tank

This indicates the fill amount compared to the maximum capacity of the tank and is displayed as a percentage value.

### How to calculate the volume of a tank?

for easy tanks reminiscent of rectangular prisms or cylinders the calculation is simple and exactly the identical as those utilized in our cylinder volume and field volume calculators. For difficult shapes comparable to dome tops, cone tops or bottoms, sloped bottom, ovals, and tablets, the tank quantity is calculated as a sum of the component simpler shapes.For illustration, the quantity of a pill tank is calculated as the sum of a sphere and a cylinder, whereas a cone bottom tank's potential is estimated via summing the quantity of the cone and the quantity of the cylinder. similarly, a dome high tank's quantity is calculated as the sum as the quantity of a half-sphere and a cylinder. The traditional volume formulas for these figures are used. certainly, if making use of our tank potential calculator all this work is carried out automatically for you.

### Calculating the volume of a liquid in a tank

The volume (in m3 or ft3) and liquid volume (in gallons or litres) of a liquid poured in a tank will also be calculated effectively assuming the tank is sitting with its backside perpendicular to the bottom surface (it isn't tilting) and there's a way to measure the liquid degree. If the tank has no noticeable stage meter or gauge and it is trustworthy to open it, its level might be measured by descending a smooth and dry rod to the backside of the tank, then retracting it and measuring the extent the liquid reached. word that this is less difficult to do with oils in comparison with water.The stuffed quantity calculation itself most of the time includes including up ingredients of the tank quantity relying on how high the liquid degree is. For instance, for a cone bottom tank, if the level is under the cone side one does not have to remember the cylinder part of the tank at all. for easy tanks one of these cylinder tank, one comfortably needs to replace the tank peak with the determined liquid peak within the average quantity of a cylinder equation. The ensuing crammed quantity can readily be modified to a percent of the total tank capacity as calculated by way of our calculator or as detailed by means of the brand specifications.
