Automatic-adjusting fog-steam nozzle provides a flow between 90 and 225 gpm (340 and 852 lpm).
<h3><u>
What is a nozzle?</u></h3>
- 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.

Single-blind procedure.
Single-blind trials occur when participants are consciously unaware of either the assigned group or important information about the material being evaluated, and the experimenter is aware of this knowledge. ..

Answer:
D) A secondary source.
Explanation:
A secondary source is any source of getting information or without the author participating in the scenes described in the text. The author may or may not be taking or writing based on his research in writing the book which can be a result of interpreting, evaluating, and analyzation of the scene described. Secondary sources can be academic/ scholarly books, articles, and commentaries, etc.
George Rawlinson's "How the Hyksos were expelled from Egypt" is a secondary source for it describes a scene that is from the past but which he is not a participant of. He is just interpreting, analyzing, and evaluating the event and then writing about it.
Thus, the <u>correct answer is option D.
