What is the capacity of the main drainage eductor?

The capacity of the main drainage eductor being 400 gallons per minute (gpm) is vital for understanding the system's efficiency and effectiveness in removing water. An eductor's capacity determines how quickly it can remove large volumes of water, which is crucial in scenarios where rapid drainage is necessary, such as during flooding or in maritime operations.

Using 400 gpm as the capacity allows for effective management of water and can significantly impact the operations involving drainage in various systems. The choice of this specific capacity often aligns with engineering design standards and operational requirements, ensuring that the eductor can handle the expected inflow of water under normal and emergency conditions.

When evaluating the other options, they might represent different pieces of equipment or variations in capability. For instance, capacities lower than 400 gpm would likely not meet operational demands in high-pressure situations, while anything higher might be unnecessary or require additional resources. Therefore, the choice of 400 gpm ensures a balance between efficiency and functionality.
