Abstract

The study of viscosity, in the area of fluid physics at a university level, is of great importance because of the various applications that are presented in the different fields of engineering. In this work an experimental method of implementation and validation is exposed, to be able to calculate the viscosity of some newtonian and non-newtonian fluids, in which the method of a sphere that descends through a fluid has been used, making Using a viscometer of our own construction, with the help of the CassyLab sensor and software of Leybold Didactics, we show the results obtained by our measuring instrument, which is intended to highlight the versatility and precision of the measuring instrument prepared by us, in addition In this work the authors want to motivate the physics laboratory teachers; to explore the use of these tools that allow you to check the topics seen in the theoretical classes. Finally, we present the hardworking results of the measurement of viscosity for different fluids, both newtonian and non-newtonian, for the latter we show the viscosity behavior as a function of temperature.
