A SIMPLE WAY TO MEASURE THE DYNAMIC VISCOSITY OF A FLUID
Keywords:
Viscosity, Experimental Methods, Calibration Curve, Practical WorkAbstract
In this paper, we measured the viscosity of different fluids, including edible oils and soaps, at a constant temperature, using two experimental methods. Namely, the falling ball and the oscillation of the mass-spring system inside a fluid. Three different masses were used to evaluate the viscosity obtained by the falling ball method. The results were very similar. More precision of the viscosity value is done using a calibration curve. The results are compared with those measured by the mass-spring system and they show good agreement. This simple way of viscosity measurement using mechanical physics concepts can be used for educational purposes such as the practical work of a bachelor.
