A duct size calculator, commonly known as a ductulator, depends on factors like the size of the space you’re heating or cooling, air flow velocity, friction loss, and available static pressure of the HVAC system.
1. Duct Size Calculator. 2. CFM Calculator 3. FPM Calculator. In this app for Calculating Duct size air flow velocity in FPM and air flow rate in CFM required to Inputs and it gives result as required duct size of Rectangular and Round Duct Types in Inches. ...
Air velocity can be calculated with the calculator below. Add air volume - q - and diameter - d - (or length a and b ). Air volume - qi - (cfm) Diameter - di - (inches) or alternatively Length side - ai - (inches) Length side - bi - (inches) Make Shortcut to this ...
This is a simple duct size calculator where you can specify the total airflow in CFM (or L/s), the aspect ratio, and either the total velocity of air or the friction loss per 100 feet (30 meters). The results include both the exact and rounded height and width (or diameter) dimensio...
Size duct by airflow: When the application first opens, select the "Duct Sizer (Size By Airflow) option to open the form that allows you to input the total airflow in CFM (L/s) and duct friction loss/velocity to display the resulting duct dimensions. Display equivalent diameter for rec...
• With no subscription the app will calculate for an air flow range between (950 and 1100 [cfm]). To activate full air flow functionality. There are four subscription options: one month, three months, six months and one year. • All subscription options will activate the "Full Air Flo...
Shipping Calculator Zip Code: Description Use this indoor mount commercial dryer duct booster for up to 4 laundromat capacity dryers (up to 1000 CFM). This fan allows you to overcome exhaust vent design restrictions. This dryer booster fan is a great solution to ducting commercial dryers to th...
When we change the design CFM to 60 we see that with a 3" duct this fan WILL NOT WORK period. When we then change the DUCT DIAMETER to 5 inches, the calculator says yeah, you're good, no limit. Watch out: using these fan calculators you can quickly get in trouble: that means hav...
