Determination of the peripheral contact angle of sessile drops on solids from the rate of drop evaporation

A study was conducted to character the initial peripheral contact angle of sessile drops on solid surfaces from the rate of drop evaporation. Data published by S.M. Rowan, M.I. Newton and G.J. McHale were utilized to determine the properties of the contact angle. A static contact radius was generated from the application of water drops on a PMMA polymer. Results indicated that the drop contact radius, initial weight and weight correlated with decreases in time.
