🔍 Key Concepts

• Centrifuge efficiency vs. flow rate – how does slowing the flow through a purifier affect separation of water/solids? • Engine fuel demand vs. treated fuel buffer – why ships keep a margin between purifier output and engine consumption. • Series vs. parallel purifier operation – how configuration affects required throughput.

💭 Think About

• If you reduce the purifier throughput while keeping engine demand the same, what happens to the residence time of fuel inside the bowl and the quality of separation? • If you increase purifier throughput too much above engine demand, what happens to separation quality and equipment wear? • What kind of percentage margin (small, medium, or very large) makes sense to ensure clean fuel, allow for maintenance, and still reliably meet engine demand?

✅ Before You Answer

• Be sure the chosen option allows purifier throughput to be slightly higher than engine consumption so a clean fuel buffer can be maintained. • Avoid options that would make the flow excessively high, which would reduce separation efficiency inside the centrifuge. • Avoid any choice that would force the purifier throughput to be equal to or less than engine demand at all times, leaving no margin for catch-up or maintenance.
