Abstract
In this lecture I introduce the basic concepts needed to understand
fluid motions at a macroscopic level. Hence, the idea of a continuous
medium and its kinematical properties are presented. Then the physical
laws governing the motion (mass, momentum and energy equation) are
derived and discussed. The concept of rheological law is introduced and
illustrated. I end this lecture with a discussion of the boundary
conditions that are needed to complete the equations of motion.
