The Air Flow & Duct Sizing Calculator allows you to calculate equivalent Round/Oval Rectangular width/depth sizes based on numerous parameters (B). Additionally any two from the following can be input and the remaining two calculated: Diameter - Velocity - Flow Rate - Pressure Drop (A).
Section A
Diameter - Velocity - Flow Rate - Pressure Drop
Example:
You know the Velocity and Flow Rate and require the Diameter and Pressure Drop values: Check the Velocity and Flow Rate boxes, enter the values, Click Calculate.
Section B
Equivalent Round/Oval Rectangular width/depth sizes based on numerous parameters
Examples:
You have the Rectangular size and need the equivalent Round: Check the Width & Depth boxes, enter the Rectangular values , Click Calculate.
You know the Round size and need the equivalent Rectangular: Check the Diameter box, enter the Diameter value, enter the desired Aspect Ratio, Click Calculate.
You know the Round size and need the equivalent Oval: Check the Diameter & Oval boxes, enter the Diameter value, Click Calculate.
