Researchers Thomas Dutta and Jay Tang from Brown University have conducted a study into how liquids drain from containers, analyzing this phenomenon both mathematically and experimentally. Their findings, published in the journal 'Physics of Fluids', indicate that the time it takes for a fluid to drain is closely related to its viscosity. This means that more viscous liquids take longer to fully escape from a vessel compared to less viscous ones.

In their experiments, they found that thin liquids, such as milk, can empty from a tilted container at a significant rate—up to 90% in about 30 seconds when the container is at a 45-degree angle. In contrast, denser liquids like olive oil take substantially longer to drain. This difference underscores the practical implications of fluid mechanics in everyday scenarios, shedding light on how we handle various liquids in our daily lives.

The research not only contributes to fluid dynamics understanding but also potentially informs various applications, from engineering to everyday culinary practices. It challenges our intuitive notions about pouring liquids and highlights the science behind common actions, inviting further exploration into fluid behavior and its applications.
