Fluid flow friction factors serve as a cornerstone in understanding and predicting the resistance encountered by fluids moving through conduits. These dimensionless parameters are essential in both ...

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 ...

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 ...

(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 ...

Nanofluidics could be used to purify water, generate energy and build nanoscale machines. But when water flows through a carbon nanotube, classical fluid mechanics breaks down, leading to puzzling ...

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 It is well known that friction between ...

Synovial joints have a cavity filled with viscous synovial fluid to reduce friction between joint bones Osteoarthritis involves degeneration of cartilage tissue at synovial joints due to changes in ...
