In Nozzle and Diffuser?

Nozzles and Diffusers
A nozzle is a device that increases the velocity of a fluid at the expense of pressure. A diffuser is a device that increases the pressure of a fluid by slowing it down. The cross sectional area of a nozzle decreases in the flow direction for subsonic flows and increase for supersonic flows.

Do nozzles and diffusers do work?

A nozzle is a device which accelerates fluid. During this process, velocity of fluid increases with decreasing pressure. A diffuser is a device which slows down fluid. ... The change of potential energy of fluid flowing into and out of nozzles and diffusers is negligible because of almost no height change.

What's the difference between a nozzle and a diffuser?

A diffuser is "a device for reducing the velocity and increasing the static pressure of a fluid passing through a system”. ... In contrast, a nozzle is used to increase the discharge velocity and lower the pressure of a fluid passing through it.
