Abstract

Water drops, from 0.05 to 0.4 cm. 3 in volume, slide without acceleration along tilted plates of stainless steel at such an angle α that W sin α = kw, if W is the weight and w the width of the drop, and k is a constant. The value of k increases with surface roughness from 48 g.sec. −2 for polished steel (average height of hills 0.02-0.03 μ) to 99 g.sec. −2 for pickled steel (average height of hills 3.1 μ). These results are accounted for by surface tension effects only, without regard to wetting. Some earlier work on friction between solids and liquids is examined.
