Correction terms for calculating surface tension from capillary rise

Surface tension of an ethane–nitrogen solution. 1: Experiment and thermodynamic analysis of the results

“…The values of b 1 and b 2 were determined by the data on the internal radii of the capillaries utilizing the Lane equation [6]. The surface tension and the capillary constant are connected by the following relation:…”

Density, Viscosity, and Surface Tension of Liquid Quinoline, Naphthalene, Biphenyl, Decafluorobiphenyl, and 1,2-Diphenylbenzene from 300 to 400 °C

“…Determination of the capillary length parameter is an iterative process using polynomial functions (Lane, 1973). The first approximation (R 1 ) to the capillary length parameter R is where ∆h is the differential height (mm) and r S is the smaller radii.…”
