Description
The resistance of a liquid to flow. Viscosity is caused by the internal molecular friction. In Cgs units, absolute viscosity is measured in centipoise (cP or cps). A hundred centipoise is one poise (P); one poise is equal to the movement of one gram of material the distance of 1 centimeter in one second. At room temperature, water has viscosity of 1.0 centipoise. In general, viscosity decreases with increasing temperature and pressure. The antonym of viscosity is fluidity.
