How many struts are present in the centrifugal fuel filter (CFF)?

The centrifugal fuel filter (CFF) is designed to remove contaminants from fuel, and its structural integrity is crucial for effective operation. The correct answer indicates that there are five struts present in the CFF. These struts play a vital role in providing stability and support to the filter's casing and internal components, ensuring that it can withstand the pressures experienced during operation.

The design with five struts is optimal for balancing strength and weight, allowing for efficient fuel flow while maintaining durability under various operating conditions. This configuration contributes to the filter's overall effectiveness in preventing clogs and ensuring a steady supply of clean fuel to the gas turbine system.

In contrast, other options suggest different numbers of struts that do not align with the established engineering design of the CFF. These options fail to reflect the necessary stability requirements and flow dynamics that are achieved with the five-strut system. Thus, the correct number of struts reinforces both the functionality and reliability of the centrifugal fuel filter in gas turbine applications.
