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.
Flux as flow rate per unit area In transport phenomena (heat transfer, mass transfer and fluid dynamics), flux is defined as the rate of flow of a property per unit area, which has the dimensions [quantity]Â·[time] â1 Â·[area] â1.
