KEY TAKEAWAYS
• Density of a liquid or fluid is its mass divided by its volume.

• The concepts of pressure mainly apply to fluids that are gaseous in nature.
• Liquids will maintain their shape in an open container.
• Pistons will exert forces that act on other areas because the pressure across the fluid system will be the same throughout the fluid.
• Buoyant force equals the weight of the water it displaces, called Archimedes principle.
• Specific gravity is equal to the density of a fluid as it relates to the density of water.
• There are cohesive forces and adhesive forces that apply to a liquid and itself or another substance.
• Flow rate is the volume of a fluid traveling per a unit of time.
• Flow can be laminar or turbulent or a combination of the two.
• There is the Reynolds number, which predicts the turbulence of a fluid or an object traveling through fluid.
• Osmosis relates to the flow of water through a semi-permeable membrane.
