Fluid mechanics is the study of how fluids move and interact with their surroundings, forming the basis for applications in aerospace, civil, mechanical, and biomedical engineering. It helps explain everything from air flow over wings to water movement in pipelines. Learning fluid mechanics can build problem-solving skills for designing efficient systems and understanding natural and industrial processes.
