Time Grain diameter

(min) (mm)

30 3.9 x 10-2

90 6.6 x 10-2

Predict what the grain diameter would be (in mm) after 199 min at the same temperature if n=2.

any ideA?

Looks like a grain growth problem. One has two sizes and two times, and one is trying to use a function. Is 'n' an exponent to a growth or diffusion equation? If so, then n=2 is a quadratic function.
