[ . A flat-blade turbine agitator with disk having six blades is installed in a tank. The tank diameter Dt is 1.83m, the turbine diameter Da is 0.61m, and Dt= H. The impeller width W is 0.122m. The tank contains four baffles each having a width J of 0.15m. The turbine is operated at 90rpm and the liquid in the tank has a viscosity of 10cP and a density of 929kgm3. 1. Calculate the required power of the mixer. 2. Calculate the required power of the mixer under the same conditions for a fluid having a viscosity of 100,000cP. Comment on your answers
