AI Thread Summary
Increasing the sedimentation velocity of 2 µm silica particles in water can be approached through various methods, as indicated by the sedimentation equation. Two methods involve adding substances to the water, while a third method does not require any additives. The discussion highlights the need for clarity regarding any limitations or constraints on the proposed methods. Understanding the specific conditions and parameters is crucial for effectively maximizing sedimentation velocity. Overall, exploring these methods can lead to enhanced sedimentation rates for silica particles in aqueous environments.

Is it possible to increase the sedimentation velocity of silica particles (2 um diameter )in water?

<br /> v = \frac{2}{9 \eta}R_s^2(\rho_{silica} - \rho_{water})g<br />

Just looking at the equation I can think of at least three methods - two require adding something to water, third doesn't.

I think your question is a little bit too vague - are there any limitations to what we can/can not do?
 

Thread 'Prove that evolution is constant (Provide at least two arguments to support your position)'

I don't get how to argue it. i can prove: evolution is the ability to adapt, whether it's progression or regression from some point of view, so if evolution is not constant then animal generations couldn`t stay alive for a big amount of time because when climate is changing this generations die. but they dont. so evolution is constant. but its not an argument, right? how to fing arguments when i only prove it.. analytically, i guess it called that (this is indirectly related to biology, im...
