Which of the following methods applies to how a vacuum is created by a jet pump or an eductor?

Correct Answer: Option C — A rapidly moving stream of fluid passing through a nozzle.

Jet pumps and eductors utilize the Bernoulli principle. A high-velocity stream of motive fluid passes through a converging nozzle, creating a low-pressure zone (vacuum) in the suction chamber. This pressure differential draws the suction fluid into the stream, where it is then carried through the diffuser for discharge.
