Fluids in Motion. For fluid. dynamics. we use a simplified . model. of an . ideal. fluid. We assume. The fluid is . incompressible. . This is a very good assumption for liquids, but it also holds reasonably well for a moving gas, such as air. For instance, even when a 100 mph wind slams into a wall, its density changes by only about 1%.. CE30460 - Fluid Mechanics. Diogo. Bolster. Newton’s Second Law. F=ma. What does this mean for a fluid? (. inviscid. ). First we need to understand streamline:. If a flow is steady a streamline depicts the path a fluid particle will take through the flow. They are tangent to the velocity vectors (in next chapter we will talk about variants of this).
