square metre per second bar

The unit $\textit{Square Metre per Second Bar}$ typically refers to a measure of fluid permeability in the context of materials science or engineering. It is the volume of fluid (in square metres) that can pass through a material in one second under a pressure difference of one bar. This unit is particularly important in fields such as petrophysics, hydrogeology, and materials engineering, where understanding the flow of fluids through porous media is crucial. A $Bar$ is not an SI unit but is a unit of pressure that is widely used in various scientific and engineering contexts. A bar is equal to $100,000\ pascals$, (symbol $Pa$), approximately equal to the atmospheric pressure on Earth at sea level.
