Major areas of fluid power
Hydraulics and pneumatics
Fluid distribution systems
Utilizes a fluid but not for power transmission purposes
What is specific gravity
How many times heavier a particular substance is than an equal volume of water (density of sub/density of fresh water)
What percentage of air is in oil
