Liquid density and other characteristics

3 Liquid density and other characteristics. Profile measurements for a symmetrical sessile drop can be used to calculate its volume and hence its density if the original mass is known and there has been no significant loss due to evaporation. As for the measurement of rLv, the volume can be estimated by measurements of the drop profile coordinates and numerical integration by using image analysis techniques (Naidich and Grigorenko 1992). Alternatively, the 

Sessile drop experiments have been used extensively to derive quantities characterising spreading and penetration phenomena, such as the work of adhesion and work of immersion, given by equations (1.45) and (1.54), using a single sessile drop experiment to measure both the contact angle and the liquid surface energy.
