• What does your book say? What do you mean by "Hydraulic Jack Oil"? Is that hydraulic fluid or are you talking about the grease you put in the grease fittings? Or something they send you looking for when they want to haze the newbie? Just go hang out in berthing and watch CCTV for a half hour or so, go back, act stupid and tell them you couldn't find it. Then laugh on the inside when they think they're laughing at you behind your back.
  • It's an incompressable fluid with a low vapour pressure. Is this for a hydraulics class or general physics? What's the context of the question?
