2 topics across all disciplines.
Pumps — head, NPSH and why cavitation is a suction problem
Centrifugal versus positive displacement, what a pump curve tells you, why NPSH decides whether a pump survives, and why most pump failures are really piping failures.
Bearings, seals and lubrication — the parts that actually fail
How a hydrodynamic journal bearing carries load on a film of oil, why babbitt is deliberately soft, what a mechanical seal is really sealing, why the seal chamber environment decides seal life, and what an API 682 flush plan is doing.
