The rate of this momentum Viscosity is a measure of the resistance of a fluid which is being deformed by either shear stress or tensile stress. Glycerin 21. oil. Finally, the conclusion should offer some suggestions for further research. Use the template provided to prepare your lab report for this experiment. Place a meter scale vertically beside the jar. What was the conclusion of the experiment? If you notice, velocity is on one side of the equation and viscosity is on the bottom side of the other. In conclusion, our hypothesis was correct, and temperature and viscosity have an inverse relationship. 10.6 Viscosity Test of Bitumen 10.6.1 Introduction Viscosity is reverse of fluidity. the frictional shear forces between them. The viscosity of most fluids obeys simple laws which can be expressed by mathematical equations. Worse yet, each professor wants something a little different. Calculate the slope of these graphs, using the equation of . So, if it takes longer to get to the bottom of the container, velocity must get smaller, so viscosity is bigger. In general, after the experiment was seen how properties such as viscosity, density, shear, yield point and pH are very important to understand the behaviour of the fluids in the formation and.
