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 ...

A team of researchers has uncovered new laws governing the flow of fluids through experiments on a technology thousands of years old: a drinking straw. This knowledge could be useful for improving ...

For future manned and unmanned NASA exploratory space missions, storage and transport of cryogenic liquids under terrestrial and microgravity conditions will play a pivotal role. Transport of ...

Nanofluidic transistors, also known as nanofluidic systems or nanofluidic devices, are innovative tools that control the flow of fluids, such as water or ions, through nanoscale channels using ...

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 ...
