You want to suspend solid pellets of sucrose (rho = 1500 kg/m-3 ) with a mean diameter of 0.1 cm in water (rho = 995 kg/m-3 , mu = 0.0089 Pa.s). The tank diameter is 1.2 m, and the impeller is 0.3 m off the bottom of the tank. The motor for your impeller turns at a maximum speed of 400 rpm. The height of the mixture in the tank is 1.2 m and the total mass of the sucrose in the mixture is 101.8 kg. You have the choice of using two six-bladed turbines, one with a diameter of 0.35 m and one with a diameter of 0.4 m. Which one should you use? Justify your answer.
