Fluid mechanics is the study of how fluids (liquids and gases) behave and interact under various forces and in various applied situations. Some key topics in fluid mechanics include:
- Fluid statics, which deals with fluids at rest
- Fluid dynamics, which deals with fluids in motion
- Bernoulli’s equation, which relates pressure, velocity, and height in a fluid system
- Viscosity, which is a measure of a fluid’s resistance to flow
- Turbulence, which is the chaotic, irregular motion of fluids
Fluid mechanics has a wide range of applications, including in civil engineering (for designing bridges and pipelines), mechanical engineering (for designing aircraft and automobiles), and biomedical engineering (for understanding blood flow in the human body).
