What is the discharge capacity of a Perijet educator?

The discharge capacity of a Perijet educator is designed to create a specific ratio between the fluid being introduced and the fluid being sucked into the system to produce the discharge. In the context of this question, option A correctly illustrates that for every 1 gallon introduced into the educator, an additional 1 gallon is sucked in, resulting in a total discharge of 2 gallons.

This example demonstrates how the educator operates effectively by using hydraulic principles to create a flow that combines the input and the suction, thus achieving a higher discharge output. The operation leverages the venturi effect, where fluid flowing through a constricted section of the educator creates a pressure drop that facilitates the entrainment of additional fluid.

Understanding this process is crucial for damage control operations, where accurately assessing and managing fluid flows can significantly affect operational efficiency during response efforts.
