Fluid Mechanics in JEE Main Exam

Fluid Mechanics in Physics refers to the study of fluids including liquids and gases. This topic in Physics deals with the movement of fluids, their interaction, and the external forces acting on them.

Bernoulli's principle accentuates the relationship between the rate of flow of a fluid and pressure. One of the most important properties of fluids is their viscosity which can be defined as the property of the fluids by which they resist deformation.

Under the JEE Main Physics syllabus, Fluid Mechanics majorly covers topics like Archimedes Principle, Bernoulli’s principle, Pascal’s law, fluid dynamics and viscosity. The topics that are mostly asked on Fluid Mechanics in the engineering entrance examination are the flow of water or other liquids or fluids, of a certain viscosity, through the pipes, buoyancy, and the law of Torricelli.
