The mechanism that moves foam concentrate into the water stream via an inline eductor is known as what?

• A. Venturi
• B. Bernoulli principle
• C. Coanda effect
• D. Magnus effect

Answer: (B)

Moving foam concentrate into the water stream with an inline eductor relies on the pressure-velocity relationship described by Bernoulli's principle. As water speeds up when it passes through the constricted throat of the eductor, its static pressure drops. That lower pressure behind the jet creates suction, drawing foam concentrate into the stream. The eductor is a Venturi-style design, which is the practical way to apply Bernoulli’s principle to entrain concentrate. So, the fundamental mechanism is Bernoulli’s principle, with the Venturi shape being the device that implements it. The other options don’t account for this suction—Coanda effect involves jet attachment to surfaces, and Magnus effect relates to spin-induced lift.
