"We found that sipping through a straw defies all the previously known laws for the resistance or friction of flow through a pipe or tube," explains Leif Ristroph, an associate professor at New York ...

Rotameter flow meters are devices that can measure the flowrate of liquids and gases. Generally, the rotameter is a tube made of plastic, glass or metal combined with a float, which responds linearly ...

Editor’s note: The Basics department this month is an excerpt from the ISA book Flow of Industrial Fluids – Theory and Equations by Raymond Mulley. Some material in this section may seem self-evident ...

Fluids play a crucial role in industrial processes like cooling, heating, and mixing. Traditionally, most industries would utilize Newtonian fluids—which have a constant viscosity—for such processes.
