A typical coal is 10 wt% ash. Most modern power plants grind their coal to an average particle size of 100 um (diameter). a. if the ash were uniformly distributed in the coal, what would be the expected size of the remaining ash particles after the coal is burned? You may assume that the density of the coal and the ash are the same.
