Detailed guide to this category

Volumetric flow rate measures how much fluid volume passes through a section per unit of time.

CFM (cubic feet per minute) and GPM (gallons per minute) are the standard practical units in US HVAC and pump industries.

What is volumetric flow rate?

Volumetric flow rate describes the volume of fluid passing a point per unit of time.

It is used for fan and ventilation capacity (CFM) and pump/irrigation flow (GPM).
