There is a well-known relationship that describes the pressure required to force liquid mercury into pores of specific diameter called the Washburn Equation: Where: P = Applied Pressure D = - 4 ( cos ) D = Diameter of the Pore = Contact Angle Between Liquid P Mercury and the Pore Wall = Surface Tension of Mercury Measuring the volume of mercury that is intruded into a sample as a function of increasing pressure permits the generation of pore size and pore volume distributions for pores accessible from a material's exterior.
