Question

Which type of fog-stream nozzle provides a flow between 90 and 225 gpm (340 and 852 lpm)?

Answer 1

Automatic-adjusting fog-steam nozzle provides a flow between 90 and 225 gpm (340 and 852 lpm).

What is a nozzle?

• A nozzle is a tool used to change the characteristics of a fluid flow as it leaves (or enters) a closed chamber or conduit, particularly to enhance velocity.
• A nozzle is typically a pipe or tube with a variable cross sectional area that is used to control, direct, or alter the flow of a fluid (liquid or gas).
• Nozzles are widely used to control the stream that emerges from them in terms of flow rate, speed, direction, mass, form, and/or pressure. The fluid's pressure energy is lost as its velocity rises in a nozzle.

A portion of the enthalpy of steam is transformed into kinetic energy as it expands from a higher pressure to a lower pressure through the steam nozzle, which is a channel with variable cross sections.

Consequently, a nozzle is an apparatus created to raise the steam's velocity.
