how do the size and the shape of the particles of a fluid affect internal friction?

Answer 1

Complex question and the standard scientific answer applies: it depends. Are you asking about a mixture of solid particles in a liquid or about the size and shape of molecules that make up the liquid? If you are asking about solid particles in a liquid, is it a suspension where brownian motion keeps the particles suspended or is it a mixture where the particles will settle to the bottom or float to the top over time?

There are scientific laws describing the settling or floating of solid particles in liquids. It depends on the viscosity of the liquid, the difference in density of the solid compared to the liquid and the size of the particles. If you want to get really scientific about it, you need more than just the average particle size is the particles are anything other than perfecly round. As I said, it is a complex question. good luck

Answer 2

Shape does not effect size, but the appearance of size is altered, as the same volume is attained. More so it is the other way around, whereas bra size effects the shape of the breast whilst wearing a bra, but without a bra, the shape is simply natural.

Answer 3

this is my guess. im gonna say friction increases as particle size decreases. and im going with friction increase as shape gets away from spherical. i did have a class on it long ago.http://www.seed.slb.com/qa2/FAQView.cfm?ID=555
