<p>What is flux in the context of fluid flow?</p>

What is flux in the context of fluid flow?

Flux (Φ) represents the volume of fluid passing through a surface per unit time

  • v= the velocity of the fluid

  • A is the cross-sectional area.

<p>How is total flux calculated when velocity varies across a surface?</p>

How is total flux calculated when velocity varies across a surface?

When velocity is not uniform, the total flux is found by integrating over the surface
