# Buoyancy Calculator

If you want to determine the buoyant force produced by a fluid like water, you can use our buoyancy calculator.

In physics, a force that moves an object in an upward direction is known as buoyancy. It is also known as upthrust or buoyant force. A buoyant force is produced when pressure is exerted by an object on any fluid type (like water). The force generated by a fluid is opposite to gravity, and it anticipates a floating object from drowning.

Moreover,

The total upward buoyancy force generated by a fluid is equivalent to the magnitude of the liquid's weight displaced by the body. In other words, we can say that the opposition of the object's weight and its magnitude is directly proportional to the liquid's volume.

## Formula of Buoyancy Calculator

To determine how to determine the buoyancy manually, you can use the formula listed below:

B = ρ * V * g

Where,

ρ = Liquid's density (measured in kg/m³)

V = Displaced liquid's volume (measured in m³)

g = Gravitational acceleration = 9.81 m/s²

B = Buoyant force or buoyancy

### Example

To understand the concept of buoyancy or to know how to calculate the buoyant force, let us have an example below:

Suppose an object is immersed in water, whereas the density of water is 1020 kg/m³. After an object is in water, the volume of the displaced liquid is equal to 0.03 m³. Find out the buoyancy of liquid.

Given data

ρ = Liquid's density = 1020 kg/m³
V = Displaced liquid's volume = 0.03 m³
g = Gravitational acceleration = 9.81 m/s²

To Find

The buoyancy of liquid = ?

Solution

To find out the buoyancy of liquid, we will use the formula listed below:

B = ρ * V * g

Putting values in the formula:

B = 1020 * 0.03 * 9.81 = 300.186 N

Note:

To calculate the centroid, you can use our Centroid Calculator.

### How to use the Buoyancy Calculator?

The steps to use the buoyancy calculator are as follows:

Step 1: Enter the value of the liquid's density in the first required input.

Step 2: Enter the value of the displaced liquid's volume in the second required input.

Step 3: The calculator will automatically display an answer on the screen.

### Calculator use

You can use our buoyancy calculator in various physics principles, such as calculating the force acting on boats or ships or any other object placed in liquid like water.
