The in-line eductor pressure loss range is?

• A. 40-60 psi
• B. 50-70 psi
• C. 70-90 psi
• D. 90-110 psi

Answer: (C)

Inline eductors use a Venturi effect to create suction, so the pressure the water loses as it passes through the eductor is what drives the intake of concentrate. That pressure drop is designed to be in the 70–90 psi range, which provides enough suction to draw the concentrate while still leaving usable discharge pressure for the flow you’re delivering. If the loss is much lower, suction may be inadequate; if it’s much higher, downstream pressure suffers and the overall flow can drop. So, the typically expected pressure loss across an inline eductor is around 70–90 psi.
