Abstract
The interfacial tension between two liquids is determined by: flowing an internal liquid (Li) through an internal flow member (2) and flowing an external liquid (Le) through an external flow member (4), with conditions being first established such that either droplets (G) of the internal liquid are formed in the external liquid, or a continuous jet of the internal liquid is formed in the external liquid, the continuous jet of the internal liquid then being formed in the external liquid or droplets of the internal liquid then being formed in the external liquid, and deducing therefrom the value of the interfacial tension between these two liquids.
