âºâº Definition: Second. A second of arc or arcsecond is a unit of angular measurement which comprises one-sixtieth of an arcminute, or 1/3600 of a degree of arc or 1/1296000 (approximately 7.710-7) of a circle.
The resistance of a liquid to flowing is its viscosity.   Viscosity is a property arising from friction between  neighboring particles in a fluid that are moving at dif â¦ ferent  velocities. In liquids, it could be considered the thickness.
Each unique material has its own behavior when subjected to flow, deformation or stress. . When studying the flow of matter, one of the most important properties is viscosity (i.e. the resistance of a fluid to flow). Fluids are characterized as Newtonian or non-Newtonian based on their viscosity behavior. Newtonian Fluids Newtonian fluids are those whose viscosity is independent of shear rate. The viscosity of these materials will remain a constant no matter how fast they are forced to flow through a pipe or channel.
