This duct sizing app was created for HVAC design professionals who might normally use a "ductulator" to select an duct sizes.
The app goes beyond simply calculating velocity, friction, or volume; It also offers a list of every even sized duct that meet the design criteria for the user to review and consideration at various aspect ratios.
The app features a highly intuitive interface which allows the user to easily adjust values with precision (without the use of cumbersome "slider" controls), or alternatively to enter the values directly with a keypad interface.
