crusher requires $130\mathrm{.}2$ kW to be able to crush a material at a rate of $198$ kg$/$h from a $210$ cm particle size down to $47\mathrm{.}0$ cm particle size. How much power would be required if the reduction requirement was changed to $0\mathrm{.}2$cm particle size. Use both the Kick$$s and Rittinger$$s laws to solve the problem the problem.
