Which term describes the fluid's resistance to flow?

Viscosity describes a fluid's resistance to flow. It measures how thick or thin a liquid is and how easily it pours. In engines and transmissions, oil viscosity tells you how well the oil will flow to form a lubricating film across moving parts; higher viscosity means a thicker fluid that resists flow more, which can protect under heavy loads but may flow less easily at cold starts. The other terms refer to different properties: pour point is the temperature at which a liquid stops pouring at low temperatures, flash point is the temperature at which its vapors can ignite, and specific gravity is the density relative to water. So the property that describes resistance to flow is viscosity.
