Objectives: The goal of this experiment was to measure and analyze the viscosity for an ideal (toluene/ P-xylene) and non-ideal (methanol/ water) solutions and to understand the differences between them this done by measuring the flow time using Ostwald viscometer. Introduction: Liquid is consisting of molecules layers that arrange one over the other. When we apply a force to a liquid, it flows. While the forces of fraction between the layers offer resistance to this flow. So, Viscosity of a liquid is a measure of a fluid's resistance to flow. It describes the internal friction of a moving fluid. At the point when a fluid has a large viscosity resists motion because its molecular makeup gives it a lot of internal friction. What's more, a fluid with low viscosity flows easily because its molecular makeup results in very little friction when it is in motion.…show more content…
The equation assumed was: F/A= ηvx/d, where η is coefficient of viscosity. From the way viscosity is defined. There is another important parameter that applies the fluid mobility is fluidity, F, which is simply the reciprocal of the viscosity coefficient: F = 1 / μ. The concept of fluidity can be used to determine the viscosity of an ideal solution. For two components a and b, the fluidity when A and B are mixed: This is only slightly simpler than the equivalent equation in terms of
