Ask an Explainer

Q:

What is the difference between a nozzle and a diffuser?

A:

A nozzle increases the velocity of a fluid, while a diffuser decreases the velocity of a fluid. Nozzles can be used by jets and rockets to provide extra thrust. Contrastly, many jet engines use diffusers to slow air coming into the engine for a more uniform flow.
