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 is the flow rate of water applied per unit area of the membrane and has units of volume/unit area/time., J, which is the flow rate of filtrate Filtrate: Filtrate is the water that has passed through the membrane., i.e., the water passing through the membrane, per unit area of membrane: Equation 1.
