Osmotic Pressure in Membrane Separation Formulas

Osmotic pressure is the minimum pressure that must be applied to a solution to prevent the inward flow of its pure solvent across a semipermeable membrane. And is denoted by Δπ. Osmotic Pressure is usually measured using the Atmosphere Technical for Pressure. Note that the value of Osmotic Pressure is always negative. Typically, the value of Osmotic Pressure is greater than 0.
