What is the revolutions per minute (rpm) for the ejector in VCHT?

The revolutions per minute (rpm) for the ejector in a Vapor-Cycle Holding Tank (VCHT) system typically operates at 1800 rpm. This speed is chosen based on the efficiency required for effectively ejecting the contents of the holding tank without compromising the system's effectiveness.

Operating at this specific rpm allows for optimal performance in terms of fluid movement and ensures that the system can maintain appropriate pressures and flow rates while minimizing wear and tear on the components. The choice of 1800 rpm aligns with standard practices in marine engineering and is common in systems designed for waste management aboard vessels, ensuring compliance with environmental regulations.

The other options, while plausible in different contexts, do not align with the established operational standards for VCHT ejectors, which are designed to operate around the 1800 rpm mark for maximum efficiency and performance.
