Which of the following design components of an air injector would result in entraining the greatest amount of air?
I.small orifice jet
II.large entrainment ports
III.low-velocity gas flow

Question

Quizplus · Accepted Answer

A small orifice jet creates a high velocity gas flow which can entrain air, while large entrainment ports provide more room for air to be drawn in. Low velocity gas flow, on the other hand, does not create enough force to draw in as much air. Therefore, the best choice(s) are options I and II, resulting in the greatest amount of air entrainment.
