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.
Caustic soda is a strong base made via the electrolysis of salt water and used in detergents, drain cleaners and other products. Caustic soda is also known as sodium hydroxide, and its chemical formula is NaOH.
Caustic soda, or sodium hydroxide, is used in the manufacture of plastic wrap, soap and paper and is the major ingredient in most oven cleaners and liquid drain cleaners. In chemical manufacturing, it is used in metal processing, oil refining and water treatment. Commercially, it is generally used a
Viscose fabric is a soft and lightweight fabric manufactured from a plant-based material called cellulose. Viscose is typically made from woody plants, such as trees and bamboo.
