What are the effects of water in hydraulic oil?

    Water is generally not miscible (dissolvable) in the oil, and water does not behave like the oil, so you will end up with blockage and other problems (improper response of equipment to pressurization), not all that different from an air bubble in general idea. Water is viscous and has a different compressability and temperature-density behavior, so lots of possible functional problems can arise. You sure as heck don't want a water bubble in the line that is supposed to transfer the pressure by pushing fluid. Water will prevent that. Brakes will fail, say.

    this is an engineering issue, so I will switch categories for you.

    The presence of water destroys both physical and chemical properties of hydraulic oil.
