Critical Surface Tension in Column Design Formulas

Critical Surface Tension is defined as the minimum surface tension a liquid must have for it to completely wet and spread over the surface. And is denoted by σ_c. Critical Surface Tension is usually measured using the Newton per Meter for Surface Tension. Note that the value of Critical Surface Tension is always positive.
