Relationship between power and number of impeller blades in straight-blade disc turbine agitators

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 \"Manual on Mixing and Mixing Equipment\" can only be used to obtain the power coefficient Np for agitators with six straight blades. Question: When the diameter Dj of the mixer is the same, what are the differences in power consumption between mixers with four straight blades, two straight blades, and six straight blades? Is power related to the number of blades? Is it a linear relationship?
