“…Physics education research shows that the conceptual difficulties to understand the phenomena associated with fluids have received relatively uneven attention. On the one hand, the difficulties associated with hydrostatic principles have been deeply analyzed by various authors, who showed how students continue to present serious difficulties in understanding the basics, even after attending university courses where these topics are covered (see [1][2][3][4][5][6] among others). On the other hand, students' understanding of ideal fluid hydrodynamics has received less attention.…”

“…• El vínculo de la presión con el mayor/menor espacio: Como se ha mostrado, las ideas de los estudiantes sobre la presión están influenciadas por el espacio que ocupa el fluido y/o por la forma que adopta en el contenedor (Besson 2004, Gallegos 1998, Goszewski et al 2013, Martin 1983, Vega 2015. Por ejemplo, en los casos 1 y 2 es evidente el empleo de esta idea, al suponer que la presión es mayor en la constricción del conducto (en el cuello del tubo de Venturi, o en la forma cónica que adopta el recipiente inclinado) y que, en consecuencia, la rapidez del flujo es mayor.…”

“…• La presión (o fuerza) es proporcional a la cantidad de fluido: Las ideas de los alumnos sobre la presión se basan en el volumen (o cantidad) de fluido contenido, considerando la existencia de una proporción directa entre estas variables (Besson 2004, Flores y Gallegos 1998, Goszewski et al 2013. En el caso 2 varios estudiantes que se inclinaron por la opción b (v A = v B ) consideraron que la cantidad de agua contenida en ambos recipientes es igual y que, por consiguiente, tienen la misma presión.…”
