Question

what is the discharge nozzle/flow nozzle write a application and work of it​

Answer 1

Answer:

A nozzle is a device designed to control the direction or characteristics of a fluid flow (especially to increase velocity) as it exits (or enters) an enclosed chamber or pipe. A nozzle is often a pipe or tube of varying cross sectional area, and it can be used to direct or modify the flow of a fluid (liquid or gas).

Answer 2

Answer:

Turbo machines like steam turbines, water turbines and gas turbines produce power by utilising the kinetic energy of the jets produced by passing high pressure steam, water and gas through the devices called nozzles. Correspond­ing to the fluids used, the nozzles are called steam nozzles, water nozzles and gas nozzles.

Some Applications of a Nozzle:

1. Nozzles are used in steam turbines, gas turbines, water turbines and in jet engines, Jet propulsion.

2. Nozzles are used for flow measurement e.g. in venturimeter.

3. Nozzles are used to remove air from a condenser.

4. Injectors for pumping feed water to boilers.

HOW IT WORKS

A nozzle is often a pipe or tube of varying cross sectional area, and it can be used to direct or modify the flow of a fluid (liquid or gas).The nozzle outlet must point downwards  to distribute the extinguishing agent effectively and to prevent pollution. The discharge pattern  of the nozzle shall be 360°.
