Fan Wind Speed Calculator

Formula

The formula to calculate the Fan Wind Speed is:

\[ WS = \frac{\pi \cdot D \cdot RPM \cdot 60}{5280} \]

Where:

\(WS\) is the wind speed (miles per hour)
\(\pi\) (Pi) is a constant approximately equal to 3.14159
\(D\) is the diameter of the fan (feet)
\(RPM\) is the revolutions per minute of the fan

What is Fan Wind Speed?

Fan wind speed is the velocity at which air is moved by a fan. It is a crucial factor in determining the effectiveness of a fan in ventilating a space or cooling an environment. The speed at which a fan moves air can be influenced by the fan’s size, shape, and RPM.

Example Calculation 1

Let's assume the following values:

Diameter of the Fan (D) = 4 feet
Revolutions Per Minute (RPM) = 1200

Using the formula:

\[ WS = \frac{3.14159 \times 4 \times 1200 \times 60}{5280} \approx 171.36 \]

The Fan Wind Speed is approximately 171.36 miles per hour.

Example Calculation 2

Let's assume the following values:

Diameter of the Fan (D) = 3 feet
Revolutions Per Minute (RPM) = 1500

Using the formula:

\[ WS = \frac{3.14159 \times 3 \times 1500 \times 60}{5280} \approx 160.65 \]

The Fan Wind Speed is approximately 160.65 miles per hour.
