Flow Rate / Differential Pressure Calculator

Flow Rate / Differential Pressure Calculator
The Flow Rate Calculator can work in two ways:

1. If you know the flow rate in cubic feet per minute (CFM) through your duct already, the Calculator will determine the differential pressure that will be seen across a flow station. Note that you still need to know the dimensions of your duct.

2. If you already know the differential pressure across your flow station, and want to determine the flow rate in the duct, the Calculator will compute this also. Note that you must also enter the dimensions of your duct.

Method One: Determining the differential pressure (you must supply the flow rate)

Circular Ducts
Square Ducts
Oval Ducts
Rectangular Ducts

Method Two: Determining the flow rate (you must supply the differential pressure)

Circular Ducts
Square Ducts
Oval Ducts
Rectangular Ducts
