🔍 Key Concepts

• Follow the flow path of the oil through the centrifuge bowl from inlet to outlets • Understand where clean oil vs. water/dirty phase normally discharge in a purifier-type centrifuge • Use the relative position of each label (K, N, V, X) to decide which one is in the outer, upper clean-oil discharge area

💭 Think About

• Trace where incoming dirty oil enters, then note which passages lead upward and inward toward the paring disc or clean-oil outlet • Ask yourself which of the labeled points is located at the end of the clarified oil path, after separation has already occurred in the disc stack • Consider how heavier and lighter liquids behave in a rotating bowl—where would the lighter clean oil collect and leave the machine?

✅ Before You Answer

• Verify that the point you choose is on the lighter-liquid (oil) side, not on the water/solids discharge side • Check that the label you select is part of a continuous passage leading from the disc stack to the outlet at the top of the unit • Confirm that your choice is not located in the sludge space or at the water discharge port at the periphery of the bowl
