Resumen
We describe a study on the conceptual difficulties faced by college students in understanding
hydrodynamics of ideal fluids. This study was based on responses obtained in hundreds of written exams
complemented with several oral interviews, which were held with first-year engineering and science
university students. Their responses allowed us to identify a series of misconceptions unreported in the
literature so far. The study findings demonstrate that the most critical difficulties arise from the students’
inability to establish a link between the kinematics and dynamics of moving fluids, and from a lack of
understanding regarding how different regions of a system interact.
