Frequently Asked Questions
What is the continuity equation?
The continuity equation states that for an incompressible fluid, the volume flow rate, area times velocity, must remain constant through a pipe, meaning fluid speeds up when the pipe narrows and slows down when it widens.
How does this relate to Bernoulli principle?
The continuity equation is often used alongside Bernoulli principle, which relates fluid velocity changes to pressure changes — as velocity increases through a narrower section, pressure typically decreases.
Does this calculation work for compressible fluids like gases?
This simplified version assumes incompressible flow, accurate for most liquids under normal conditions, but compressible gas flow at high velocities or pressure changes requires more complex equations accounting for density changes.
