## Definition

a small part at the end of a pipe or hose that controls how liquid or gas comes out. You use it to aim the spray or change how strong the flow is.

For teachers: a projecting part with an opening, often at the end of a pipe or tube, used to direct or control the flow of a fluid. Typically designed to increase velocity or regulate the spray pattern.

## Examples

- He pointed the nozzle of the hose at the flowers.
- The firefighter adjusted the nozzle to create a wide mist instead of a powerful stream.
- Precision engineering of the fuel injection nozzle ensures that the petrol is atomised into a fine spray, allowing for more efficient combustion within the engine cylinder.
