🔍 Key Concepts

• Pressure drop across filters in high-flow lube oil systems • Relationship between filter surface area and system size/flow rate • How large engines handle continuous filtration vs. bypass systems

💭 Think About

• In a very large lube oil system with high flow rates, what happens to the pressure on each side of a fine filter element? • Which of these options would realistically prevent you from scaling a small filter design up to a very large engine system? • Think about which issue becomes a design limitation as flow increases, rather than a maintenance or ‘nice to have’ concern.

✅ Before You Answer

• Compare which option would cause a system design limitation rather than just extra maintenance work • Ask: which problem gets worse as flow and system size increase? • Eliminate any choices that are unlikely at normal working pressures in a properly engineered marine lube oil system
