Fluid dynamics is used in a wide range of fields. Fluid flow through pipes and in blood vessels are important both in engineering and physiology. Heated convective air, motion of electrically conducting fluids give rise to currents which are used in the design of magnetohyrodynamics(MHD) generators and pumps. Wind which is air in motion gives rise to Wind energy utilization. In general, Fluid dynamics find its use in Civil, Mechanical, Chemical and Petroleum engineering, Industry, Food processing and a myriad other processes.
