"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 ...

Interactions between molecules and electrons in carbon nanotube walls can cause 'quantum friction'. (Courtesy: Geoffrey Monet, ENS) When water moves through nano-sized channels made of carbon, its ...

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 ...

IN a communication published recently on “Flow of Water through Very Narrow Channels”, Reekie and Aird 1 give results obtained from measurements of the flow of both water and air through plugs of very ...

In the 1960s, drillers noticed that certain fluids would firm up if they flowed too fast. Researchers have finally explained why. Fluids can be roughly divided into two categories: regular ones and ...
