Document Summary
Newtonian (or classical) mechanics presupposes that all the observations are performed within an inertial (or galilean) frame of reference. Since the foundation of fluid mechanics is newtonian mechanics, fluids in motion should also be described within an inertial frame of reference. It would have been indeed impractical to refer every fluid motion to the last coordinate system. However, for the vast majority of fluid mechanics problems, one can assume the earth to be an inertial frame, without suffering a substantial loss of accuracy. Off course, if one deals with large-scale terrestrial phenomena such as oceanic or atmospheric circulations the previous assumption is invalid. Often the solution of some important fluid problems requires the utilization of non-inertial frames of reference. 0 i a y f j f x p/a x f/a. Since there is not much movement observed in that particular location of the universe. Consider the two frames of reference shown in fig.
