## Blowing Force Formula

The following equation is used to calculate the Blowing Force.

BF = Da * A * V^2

- Where BF is the blowing force (N)
- Da is the density of air (kg/m^3)
- A is the contact area (m^2)
- V is the velocity of the air (m/s)

To calculate the blow force, multiply the density of air by the contact area, then multiply by the velocity of the air squared.

## How to Calculate Blowing Force?

Example Problem:

The following example outlines the steps and information needed to calculate Blowing Force.

First, determine the density of air . In this example, the density of air is found to be 1.225 kg/m^3.

Next, determine the contact area. For this problem, the contact area is found to be 5 m^2.

Next, determine the air velocity. In this case, the air velocity is measured to be 10 m/s.

Finally, calculate the Blowing Force using the formula above:

BF = Da * A * V^2

BF = 1.225*5*10

BF = 61.25 N
