Viscosity is a term used to describe the measure of a fluids resistance to flow. The internal friction of a fluid in motion and it's unofficial "thickness" can also be described in terms of the viscosity of a particular fluid.
The viscosity of water is 1.0020 millipascal seconds at 20°C. The viscosity of water, and other substances, can change with a difference in temperature. Water has low viscosity compared to other fluids.
Viscose is a fabric made from cellulose or wood pulp. Also called rayon in the United States, viscose is made using a process involving caustic soda and a spinneret.
Viscosity describes a fluid's resistance to flow. The thicker the fluid, the slower it flows and the higher its viscosity. The viscosity of a lubricant such as oil affects how it reduces friction and transfers heat.
Viscose can be washed by hand or by using the delicate cycle on a washer. Viscose should be washed in cold water to avoid fading or shrinking.
Sulfuric acid is one example of a caustic substance. Ingesting caustic substances can result in serious injuries and can even be fatal in extreme cases.
Dropping a marble or ball bearing through a liquid is a simple method for measuring viscosity, while an Ostwald Viscometer is more complex and more accurate. The ball bearing method involves more rigorous calculations than the viscometer.
