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.
How to Calculate Flow Resistance for Liquids. Liquid Flow Lohm Laws. The Lohm Laws predict the actual performance of fluidic devices beyond the definition conditions of water at 25 psid and 80Â°F. In Liquid Flow several variables must be related, including: I = Flow rate.
