131. How does a water aspirator pump work?
The water aspirator pump is essentially a pipe with a narrowing in it. As water flows through that narrowing, it speeds up and its pressure drops—it's exchanging its pressure energy for kinetic energy. A tiny opening in the side of the narrowing allows water or air to enter the high-speed flow. Since the pressure in that high-speed flow is very low, atmospheric pressure pushes fluids through the tiny opening and into the flow. The flow pumps fluids through the opening and into the water stream. If you connect a hose to the tiny opening, you can suck chemicals up the hose and into the water stream.
