(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 ...
Space to play or pause, M to mute, left and right arrows to seek, up and down arrows for volume. Friction is a force that exists when two surfaces rub up against each other. For example, this cup on ...
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 ...
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 ...
• 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 ...
