2. Some rotors of rheometer are marked with shear rate coefficients, such as conical rotors. You need to check the product specifications.
3. Shear rate = shear rate coefficient (this is the specification set by the manufacturer at the time of production, and it is known data) multiplied by the rotational speed (RPM).
So you should not find the coefficient, but find the coefficient of the shear rate of the rotor you are using, and then calculate it according to the above formula.
