Question 3 (35 points). Larsen Pharmaceutical company has designed a batch process to create a crystalline API. On the benchtop, the reactor (also known as a crystallizer) used in successful production has the following properties: an overall tank diameter of 1.0 m, a liquid height of 2.0 m, and an impeller diameter of 0.4 m. You are tasked with scaling the reactor up to a volume of 100 m³. The fluid in the crystallizer has the following properties: viscosity of 0.001 Pa*s and density of 1000 kg/m³. (Recall that Pa = kgm-1s-2) The reactor uses a pitched blade turbine to maintain the appropriate suspension of catalysts, which moves at a speed of 18 revolutions per second. a. (5 points) Determine if we can use the reported Np for a pitched blade turbine. b. (15 points) Calculate your new, scaled up tank diameter, liquid height, and impeller diameter. c. (15 points) Calculate the speed of the new impeller needed to maintain the turbulent energy dissipation.
