What gallon per minute (GPM) vari-nozzle is used with an in-line eductor?

• A. 75 GPM
• B. 95 GPM
• C. 150 GPM
• D. 200 GPM

Answer: (B)

The correct choice is based on the typical flow rate required for an in-line eductor to function effectively. Eductors are devices used to mix or inject a substance into a fluid, often taking advantage of the Venturi effect. The 95 GPM vari-nozzle is commonly used because it strikes a balance between providing sufficient flow to create the necessary suction for mixing while not exceeding the operational limits of standard firefighting or water supply systems. This specific flow rate allows for optimal performance in applications such as foam application or other fluid mixing processes where the eductor relies on consistent and reliable water flow. The other flow rates, while potentially viable for different applications or equipment, do not align as closely with the standard operational requirements when using an in-line eductor, which is why they are less suitable in this context.
