Q4 (Liquid Mixing): You work as an engineer in a factory that produces substance A. For the production of this substance, the liquid mixture with a density of 803.4kg/m3, a viscosity of 2.26103 Pa.s should be mixed. As a result of your literature research, you determined that the mixing process should be carried out at 0.8rpm, with a 3-blade marine impeller (p=D) with a diameter of 1m and a mixer height of 1.25m. For this process, you can use a 0.15kW motor and a metal tank with a diameter of 3m and a height of 7m. Calculate the power for the unbaffled tank by taking the height of the liquid 3m
