A Method to Estimate the Contact Angle of a Drop Spread upon a Flat Surface When It Is Otherwise Too Flat to Measure.
Abstract
A method of estimating the contact angle of a sissle drop on a clean, level surface, is developed for drops whose profiles are so low that the contact angles are too small to measure. A simple geometric relationship between the drop's volume and its contact angle is demonstrated, both mathematically and by experiment, and is shown to hold within the limits defined by the conditions.
