It is important to understand that there is no simple relationship between viscosity and particle size that covers all types of liquids. Liquid viscosity is caused by forces between its particles, ...

Water is one of the most abundant substances on Earth and partakes in countless biological, chemical, and ecological processes. Thus, understanding its behavior and properties is essential in a wide ...

Water pours into a cup at about the same rate regardless of whether the water bottle is made of glass or plastic. But at nanometer-size scales for water and potentially other fluids, whether the ...

The term “Nanofluids” was first proposed by Choi of Argonne National Laboratory USA in 1995, which meant nanoparticle fluid suspensions. After which, this interdisciplinary field has developed ...

When seawater gets cold, it gets viscous. This fact could explain how single-celled ocean creatures became multicellular when the planet was frozen during “Snowball Earth,” according to experiments.

The flow of fluids is one of the most complex, beautiful, and amazing things in physics. Slow motion pictures of drops landing on water or of two fluids mixing can be simply gorgeous. Even more ...
