What is the primary purpose of an eductor?

The primary purpose of an eductor is to create a vacuum for fluid transfer. An eductor works on the principle of jet propulsion and uses a high-velocity stream of fluid to create a low-pressure area, effectively drawing in another fluid. This makes it particularly useful for pumping out water or other liquids, often from spaces that may not be easily accessible or where traditional pumps may not function effectively.

The design allows it to be portable and to operate without needing a complex mechanical setup, making it valuable for damage control operations, especially in marine environments. The other options pertain to different functions that do not align with the primary operation of an eductor. While cooling equipment, increasing fluid pressure, and measuring fluid levels are important aspects of fluid management, they do not represent the primary function of the eductor itself. Being familiar with the eductor's role can greatly enhance the effectiveness of damage control efforts, particularly in emergency situations.
