The objective of this article is to analyze the applications of double integrals in the calculation of fluid flow density in a vector field. The qualitative approach was applied, likewise, the documentary design was used because it is a descriptive study, in which basic concepts of integrals, vector fields, fluids, volume of solids, volumetric flow, properties and types of educational evaluations that are part of the backbone of this work are analyzed. Data collection was through the observation of videos on the YouTube platform, interviews with university teachers, textbooks and journal articles related to the topic of double integrals, vector fields and fluids. Likewise, for the analysis of the information it was necessary the triangulation of theories, taking into account the different points of view of the researchers regarding the topic in order to reach a conclusion and give a solution to the two unpublished problems posed through the analysis of different physical and mathematical variables, which are related to the interdisciplinary nature of integral calculus, vector calculus and fluid mechanics. For the analysis of the results it was necessary to solve two problems in order to put into practice everything analyzed and described in the theoretical reference and thus fulfill the objectives of the work.
