Which of the following methods applies to how a vacuum is created by a jet pump or an eductor?
AI Explanation
The correct answer is C) A rapidly moving stream of fluid passing through a nozzle.
In a jet pump or eductor, a rapidly moving stream of fluid, such as water or air, is directed through a nozzle. This creates a low-pressure area or vacuum, which draws in and entrains another fluid, such as air or water. The high-velocity fluid stream passing through the nozzle is the key mechanism that applies to how a vacuum is created in these types of pumps.
The other options are incorrect because: A) A propeller does not create a vacuum in a jet pump or eductor; B) A reciprocating plunger applies direct force, rather than creating a vacuum; and D) Centrifugal force is not the primary mechanism for creating a vacuum in these types of pumps.
