Web20. The procedure using pure water is faster than the weight calibration, but there is the danger that the surface tension of the water (e.g. 72.3 mN/m at 23 °C) is altered by traces of impurities, surfactants for instance. The calibration factor, b, is given by where o = value cited in the literature for the surface tension of water (mN/m), and WebThe surface tension γ is defined as the force along a line of unit length. The force is parallel to the surface and perpendicular to the line. Surface tension is therefore measured in units of N/m in SI units. The surface tension γ for different surfaces is listed in the table below. Picture a soap bubble.
