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 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 defined by where: • is the shear rate, measured in reciprocal seconds; • v is the velocity of the moving plate, measured in meters per second;
