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 ...

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 ...

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.

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 ...

This January, a group of researchers in Cornell’s Collective Embodied Intelligence Lab overcame a barrier in soft robotics by designing and modeling a system that takes advantage of fluid viscosity.
