Physics of mixing different powders

  • #1
Let's say you have two powders (say, flour and brown sugar) which are to a certain degree mixed with each other. Is there a commonly accepted parameter that determines how well mixed this mixture is? Obviously there's a difference between having the mixture so unmixed that you can see a line dividing one powder from the other, and having the mixed so well mixed it's a shade of light brown rather than brown and white, but I don't know how I'd determine that quantitatively.

To my knowledge, there is no standardized way of measuring how well mixed two powders are.

However, there are many ways of measuring it this, how do you think it could be measured?
