Enter the density of air, the area of impact, and the velocity of the air into the calculator to determine the blowing force.

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)

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
