Results have been reported on the performance of a crystallizer operating on sodium chloride. Results from one experiment are 

Tip speed u_T = 1.350 ft/min             Retention time = 1.80 h 

Time between passages, or turnover time = 35 s

Size distribution parameters are 

n = 1.46 x 10⁶ number/cm⁴            B = 1.84 number/cm³-s 

Crystal density = 2.163 g/cm³

Calculate the dimensional constant K_g. using the units specified above, and the growth rate in millimeters per hour.
