AI Thread Summary
Ferrofluid surfactants create steric and electrostatic repulsions to counteract van der Waals and magnetic forces, preventing particle clumping. Steric repulsion occurs when particles are kept apart due to the physical presence of surfactant molecules. This mechanism is crucial for maintaining the stability of ferrofluids. Understanding these interactions is essential for applications in various fields, including engineering and materials science. The provided links offer additional information on steric effects for further clarity.

hi i am a bit confused as to what Steric repulsions are i know that a Ferrofluid surfactant makes Steric repulsions or electrostatic repulsions to counter the van der Waals and magnetic forces to stop stops the particles from collecting or clumping
many thanks for any help

Thread 'The Physics of unloading sand from a barge'

I think it's easist first to watch a short vidio clip I find these videos very relaxing to watch .. I got to thinking is this being done in the most efficient way? The sand has to be suspended in the water to move it to the outlet ... The faster the water , the more turbulance and the sand stays suspended, so it seems to me the rule of thumb is the hose be aimed towards the outlet at all times .. Many times the workers hit the sand directly which will greatly reduce the water...
