An air blower's capacity is a critical factor in maintaining airflow efficiency in various industrial and residential systems. This Air Blower Capacity Calculator helps determine the volume of air moved by a blower, ensuring proper selection and operation.
Formula
The formula to calculate air blower capacity is:
Air Blower Capacity (Q) = (Fan Speed (N) × Fan Diameter (D)) ÷ 2
How to Use
- Enter the fan speed in revolutions per minute (RPM).
- Input the fan diameter in meters.
- Click the "Calculate" button to obtain the air blower capacity in cubic meters per minute.
Example
For a fan operating at 1000 RPM with a diameter of 1.5 meters:
Q = (1000 × 1.5) ÷ 2 = 750 cubic meters per minute.
FAQs
- What is the purpose of the Air Blower Capacity Calculator?
