Question:

In the scaleup of a stirred-tank process involving a shear-sensitive suspension, it is important to keep the maximum shear rate below a critical value. 

(a) If scaleup requires a 10-fold increase in the tank diameter and if the power per unit volume and geometric ratios are kept constant, by what factor will the shear rate change? 

(b) What could be done to keep the maximum shear rate unchanged?
