Calculate volumetric flow rate from velocity and cross-sectional area

Flow Rate
0
Formula: Q = v × A
Where Q is volumetric flow rate, v is flow velocity, and A is cross-sectional area.
About Flow Rate: Volumetric flow rate measures the volume of fluid passing through a cross-section per unit time. This is fundamental in fluid dynamics, HVAC systems, pipe design, and many engineering applications.
