Movement of fluids through a selectively permeable membrane caused by hydrostatic pressure is referred to as ____________ .

Filtration: The process by which the solid particles are separated from liquids/gas (i.e. fluids) through a semi permeable membrane (filter) according to its concentration gradient (i.e. movement of particles from high concentration to the lower concentration) is called filtration.

The process of filtration is enhanced by the hydro-static pressure (i.e. pressure exerted by the fluids).
Examples: Filtration has so many practical examples like vacuum cleaner and air conditioner are the examples of filtration which uses a filter to remove dust particles from the air through hydro-static pressure.
Rate of filtration process is proportional to the hydro-static concentration caused by concentration gradient i.e. increasing hydro static pressure increases the rate of filtration process and decreasing the hydro-static pressure will decrease the rate of filtration process.
