Rectangular Duct Calculator
Designing an efficient cooling or ventilation system requires careful consideration of airflow. The Rectangular Duct Calculator helps you determine the recommended dimensions for a rectangular duct based on two essential factors:
- CFM (Cubic Feet per Minute): CFM measures the volume of air flowing through the duct every minute. It indicates how much air is needed to cool or ventilate a space effectively. Input the desired CFM value to represent the desired airflow.
- Velocity (feet per second): Velocity signifies the speed at which air travels through the duct. Proper airflow distribution is crucial for efficiency. Input the desired velocity value to determine how fast the air should move.
