“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 ...

Whether it is oil gushing through pipelines or blood circulating through arteries, how liquids flow through tubes is perhaps the most fundamental problem in hydrodynamics. The challenge is to maximize ...

Scientists have created a model alveolar system that mimics the breathing action of the human lung and allows visualization of flow patterns within the alveoli. The chip they designed includes tubes ...

One of the most familiar techniques for teaching elementary electricity is to compare the flow of electrons through wires to the passage of fluids through pipes. The analogy is so valid that ...

One milligram per hour: fluid flow can be measured with great precision using a tiny ‘wobbling’ tube with a diameter of only 40 micrometers. Thanks to a new technique, the sensor, which makes use of ...

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 ...

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 ...

Fluid-handling devices are not basically concerned with the modulation of power, but only with the movement of fluid. Choosing a fluid-handling valve used to be easy, because each one had its own area ...
