Good emulsification behaviour in a turbine oil means the oil

  • A.separates rapidly from water
  • B.mixes readily and permanently with water
  • C.dissolves water completely at all temperatures
  • D.prevents water from entering the system at all

Answer: A

Water inevitably finds its way in, and an oil that separates lets it be drained from the reservoir instead of circulating as an emulsion that corrodes and impairs the film. A cutting fluid, by contrast, is required to emulsify readily.
