Abstract: The surface area of a liquid in a circular tube approximates to about 2% the area represented by an oblate spheroid that has the tube radius and the meniscus height as its major and minor semiaxes, respectively. Over much of their range, the tables of Bashforth and Adams appear to represent coordinates of an ellipse within about 4%.
