Relationship between power of disc turbine stirrers and number of blades

Hello, friends! Currently, there is a reaction vessel that requires a disc turbine agitator. Due to considerations related to mixing intensity, it is necessary to design and manufacture agitators with four straight blades or two straight blades. When calculating the mixing power for these agitators, the Np-Re curve provided in the \"Handbook of Mixing and Mixing Equipment\" can only be used to obtain the power coefficient Np for turbines with six straight blades. Question: Given the same mixer diameter Dj, what is the difference in power consumption between four-blade, two-blade, and six-blade mixers? Is power related to the number of blades? Is it a linear relationship?
