Enter the radius, height, and density of the material into the calculator to determine the load capacity of a Sonotube. This calculator can also evaluate any of the variables given the others are known.

## Sonotube Load Formula

The following formula is used to calculate the load capacity of a Sonotube.

LC = (π * r^2 * h * d) / 1000

Variables:

- LC is the load capacity (kN) π is a constant (approximately 3.14159) r is the radius of the Sonotube (m) h is the height of the Sonotube (m) d is the density of the material (kg/m^3)

To calculate the load capacity of a Sonotube, multiply the square of the radius by the height of the Sonotube and the density of the material. Multiply this result by the constant π. Finally, divide the result by 1000 to convert the load capacity from Newtons to kiloNewtons.

## What is a Sonotube Load?

A Sonotube Load refers to the weight or force that a Sonotube, a type of cylindrical concrete form, can support or bear. This load capacity is determined by factors such as the tube’s diameter, wall thickness, height, and the type of material it is made from. It is crucial to know the load capacity of a Sonotube to ensure safety and stability in construction projects.

## How to Calculate Sonotube Load?

The following steps outline how to calculate the Sonotube Load Capacity:

- First, determine the radius of the Sonotube (r) in meters.
- Next, determine the height of the Sonotube (h) in meters.
- Next, determine the density of the material (d) in kg/m^3.
- Next, gather the formula from above = LC = (π * r^2 * h * d) / 1000.
- Finally, calculate the Sonotube Load Capacity (LC) in kN.
- After inserting the variables and calculating the result, check your answer with the calculator above.

**Example Problem : **

Use the following variables as an example problem to test your knowledge.

radius of the Sonotube (r) = 0.5 m

height of the Sonotube (h) = 2 m

density of the material (d) = 1500 kg/m^3
