The problems of the development of algorithms to process experimental
results obtained by the sessile drop method are discussed. Algorithms
are based on the numerical solution of the Young-Laplace equation and
the regularization method for Dorsey formula. A software package for I
BM PC AT has been developed. The results of calculations for droplets
formed in a cup (liquid Fe) and on a plate (slag CaO-B2O3) are given.
