This work analyzes liquid drains from containers in effective zero-g conditions aboard the International Space Station (ISS). The study digitizes hours of archived NASA video records from experiments conducted between 2010-2015 to quantify transient interface profiles and volumetric flow rates during single exit port draining flows from containers with interior corners. The data is benchmarked against lubrication models for slender flows, validating some geometry-dependent dynamical interface curvature boundary conditions while invalidating others. All analyzed data is publicly available as MATLAB files.
