Understanding and controlling the flow of liquids at the nanoscale is currently a subject of great interest. More than 100 papers describing work in nanofluidics have been published in the past five ...

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 ...

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 ...

The main application of the rotameter flow meter is to measure the flowrate of liquids and gases. It is composed of a plastic, metal or glass tube and float. The float response to flowrate changes is ...

Blood may be thicker than water, but in a narrow enough tube, both liquids flow like treacle. This sluggish behaviour arises because, as you reduce the size of the channel, friction between the liquid ...

Physicists surprised to find that in specially coated tubes, the more viscous a liquid is, the faster it flows. It's widely known that thick, viscous liquids -- like honey -- flow more slowly than low ...

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 ...

Recent advances in flow sensing have resulted in more accurate, durable, and economical meters. Increasingly important is the ability to interface meters with a computer for instantaneous flow readout ...

Scientific progress is not usually straightforward. Researchers pursue and abandon lines of inquiry. Results languish. Theories take decades to cohere. But sometimes the accumulation of scientific ...
