Viscosity is one of the most important properties in determining fluid dynamics for many applications. This research is aimed to develop a viscometer apparatus for physics experiments based on the rotation method. A ATmega328-microcontroller and FC-33-5V phototransistor sensor were used to detect the angular motion of the blades. The rotation of 2-blades stirrer of 40 mm long and 30 mm wide stainless steel plate was measured to determine the viscosity value, while the data measurement is processed using a microcontroller and LCD screen for displaying the result. Calibration of the apparatus is carried out using a tachometer based on the rotation measurement resulted in an error of 0.17 %. The viscometer was tested using samples of distilled water, Turalik-52 oil, engine oil STP 15W40, and Yamalube 10W40 that give an error of 1.62 %, 6.75 %, 6.22 %, and 8.23 %, respectively. Based on these results, the rotation-based viscometer can be used as a simple apparatus for education learning tools in understanding the concept of viscosity. [ABSTRACT FROM AUTHOR] |
