Plot curves of Y vs. x for x=1.6 cm and n = 0.5, n=0.75, n=1. Let x range from 0.2 to 2.2 cm in increments of 0.2. Which n value gives greater variation in particle size (difference between the highest and lowest points on the curve, or difference in Y)? So what can you conclude that n tells you about a particle size distribution? Plot curves of Y vs. x for xo=1.0, xo=1.6, xo=2.0 cm and n=1. Let x range from 0.2 to 2.2 cm in increments of 0.2. Which X, value gives the coarsest size distribution? So what can you conclude that xo tells you about a particle size distribution?
