Da rpm a shear rate

WebShear rate is the rate at which a progressive shearing deformation is applied to some material. The shear rate for a fluid flowing between two parallel plates, one moving at a constant speed and the other one stationary (Couette flow), is related to the velocity of the moving plate and the distance between the two parallel plates Related formulas Web(1) shear rate influences the average apparent viscosity of non-Newtonian fluids and hence affects power absorption, mixing characteristics and mass transfer phenomena …
