Pendant Drop Tensiometry for Measuring Surface Tension Effects of Sinus Rinses on Rhinosinusitis Mucus: A Pilot Study* Saline irrigations play an important role in treating chronic rhinosinusitis.* Residual irrigation fluid may alter the cohesive properties of sinonasal mucus, thereby affecting patient ...
In such measurements, light passes from the pendant drop through a surrounding bulk phase, an optical window and air to reach the lens of the camera system. The relation between object and image size is typically determined by calibration and, if the refractive indices of any of the materials...
The pendant drop tensiometry is a preferred primary method for measuring interfacial tension (IFT) or surface tension. In a typical experimental setup, Gravitational pull opposes an interfacial tension forces to cause a liquid drop to develop into a pendant-like shape. The process comprises ...
WaterPropylene glycolNew optimized experimental setup based on pendant drop tensiometry was developed, and a mathematical model designed to fit the experimental data was used to determine the diffusion coefficients of binary systems at elevated pressures and temperatures. For the first time, the ...
