Fluid dynamics; is the study of fluid in motion.

Fluid; is any matter that flow such as liquid and gaseous. Or is a 

substance that cannot maintain its own shape but takes the shape of its 

container. 

Ideal liquid is an incompressible and non-viscous liquid. In actual 

practice there is no liquid which is ideal liquid. That is why Fluid laws 

assume idealized fluids that cannot be compressed.
