## Steel Tank Formula

The following formula is used to calculate the weight of a steel tank.

W = pi * (Do/12-Di/12)^2/4*h*d

- Where W is the weight (lbs)
- Do is the outer diameter (in)
- Di is the inner diameter (in)
- h is the height (ft)
- d is the density (lbs/ft^3)

To calculate the steel tank weight subtract the volume of the inside of the tank from the volume of the total tank including walls, then multiply by the density.

## What is the weight of a steel tank?

Definition:

The weight of a steel tank will depend on the height and wall thickness of the tank. This along with the density, which is 490 pounds per cubic foot, gives the weight of the steel tank.

## How to calculate weight of a steel tank?

Example Problem:

The following example outlines how to calculate the weight of a steel tank.

First, determine the inner diameter. For this example, the inner diameter is measured to be 5 inches.

Next, determine the outer diameter. This outer diameter is 12 inches.

Next, determine the height of the tank. The height is measured to be 2ft.

Finally, using the information above, and the density of 490 pounds per cubic foot, calculate the steel tank weight.

W = pi * (Do/12-Di/12)^2/4*h*d

W = 3.14159* (12/12-5/12)^2/4*2*490

W = 261.908 lbs
