(Nanowerk News) For 15 years, scientists have been baffled by the mysterious way water flows through the tiny passages of carbon nanotubes — pipes with walls that can be just one atom thick. The ...

1.1 What is friction? Take this everyday example: when a coffee mug rests on a flat table, the kinetic frictional force is zero. There is no force trying to move the mug across the table, so there is ...

Imagine walking from one side of a swimming pool to the other. Each step takes great effort -- that's what makes water aerobics such effective physical exercise. Imagine walking from one side of a ...

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 ...

It is well known that friction between lubricated surfaces is a chief source of energy losses in fluid power systems. Now, help is on the way due to research taking place within the Engineering ...

Liquid assets: how to make coins flow like a fluid Friction in one part of a system can be reduced by boosting friction elsewhere. That is the curious and counterintuitive conclusion of Yasinul Karim ...

Although they might share similar purposes, you can't swap or mix CVT fluid and Automatic Transmission Fluid due to their distinct ways of working.

• Excessive seal friction wastes energy, accelerates wear, and can lead to premature failure. • Too little friction makes a seal prone to leak. • Pressure-activated hydraulic seals minimize both ...
