Abstract

Dynamic fluids have a stationary flow, where the volume of fluid flowing in each cross-section of the pipe in a specific time interval is the same even though the pipe is widening or narrowing but the fluid velocity is different. When a fluid moves through a section where the velocity and height above the surface change, the pressure in the fluid changes. Understanding led to errors in understanding the concept, so this research was carried out to identify the profile of misconceptions in a dynamic fluid material. Students misconceptions were detected using a three-tier diagnostic test with data analysis using the Certainty of Response Index (CRI). This research is quantitative descriptive research. The respondents of this study were students of class X of senior high school who had received dynamic fluid material. Based on the results of this research, showed that students experienced moderate category misconceptions on dynamic fluid material with the highest level of misconceptions, namely the concept of continuity equation analysis, and the lowest misconception in the analysis of the concept of water flow discharge.
