Greenheck program helps figure airflow formulas
Greenheck’s new mobile application features a fan law calculator and a “ductulator” to help engineers and contractors make quick calculations.
The Greenheck Toolbox App is available for the iPhone, iPad and Android-based smartphones and tablets.
The application’s fan law calculator feature allows users to input existing specifications for rotations per minute, cubic feet per minute, static pressure and horsepower. Users can also input measurement changes, and the remaining values will automatically calculate using standard fan laws.
With the ductulator, users can size HVAC duct by inputting duct shape, rounded dimension, air temperature, elevation and roughness. Results are automatically calculated and displayed once selecting the velocity or friction factor and inputting the volume, velocity and aspect ratio.
