These relationships are much easier to study with everyday sources like kitchen liquids, however. Dutta used the equations to predict how long it takes fluids with different viscosities to progress along a downward angle. Tang often finishes a night’s kitchen cleaning by letting his wok sit for a moment on the counter. Tang and Dutta can now employ these calculations to help further their research into bacterial dynamics. It just happens to also be the everyday fluid physics of the kitchen,” said Tang.
