How do you find viscosity of given liquid by oscillating disc method?

To find the viscosity of a liquid using the oscillating disc method, you would typically place a disc in the liquid and oscillate it at a constant frequency. By measuring the torque required to keep the disc oscillating, along with other parameters like disc radius and frequency, you can calculate the viscosity using the equation specific to this method. This method is suitable for measuring the viscosity of Newtonian liquids.
