摘要：

Power measurements indicated that in the laminar flow regime the power (P) consumed during the agitation increased with speed of agitation (N) according to the relationship P =where n is the flow behavior index and K1 is a constant which depends on the assembly and fluid consistency index. For the helical ribbon-screw agitators, the constant ks relating average shear rate in the mixer to the agitator speed (γ = ksN) was found to be 30.6. Using this value of ks and flow behavior index n, PoRe and PoRe'may be related as The power consumption was found to be linearly proportional to the liquid depth. © 1979, American Chemical Society.
