What characteristic feature does a jet pump have?

A jet pump operates based on the principle of fluid dynamics, leveraging fluid velocity to create suction. When a high-speed jet of fluid is introduced into a mixing chamber, it creates a drop in pressure that allows surrounding fluid to be drawn into the system. This is a key characteristic of jet pumps, distinguishing them from other types of pumps like positive displacement pumps that rely on mechanical means to move fluids.

The reliance on fluid velocity is central to its operation, as the flow of the jet effectively entrains additional fluid, facilitating the mixing and lifting of fluid from a source. This principle allows jet pumps to be efficient for applications where suction is needed without the complications of mechanical parts typical in other pumps.
