Fluid dynamics is a rich and complex field of study with turbulence and chaos in its wake. For our purposes, however, just as in the case when we first introduced Newton's laws where we learned how to describe motion on "frictionless" surfaces, we will focus primarily on ideal fluids (fluids without friction (no viscosity) and fluids that do not rotate). The two main equations we will use are the continuity equation (what flows in must flow out) and Bernoulli's equation (conservation of energy). As a result, we will be able to understand the connection between fluid motion and pressure.
