How many jets does the S-type educator have?

The S-type educator is designed with a single jet to create a vacuum for the purpose of suction. This single jet is critical for the educator's operational efficiency, as it utilizes a specific flow of water to generate a low-pressure environment that can draw in additional fluids, such as seawater or other firefighting agents. The simplicity of having one jet makes the S-type educator easy to operate and maintain, which is especially advantageous in damage control scenarios on a ship. Understanding the design and function of the S-type educator is essential for effective damage control tactics, especially regarding fluid transfer and firefighting operations.
