Fluid Mechanics
The field of fluid mechanics examines the behavior of fluid systems and objects moving through fluids, such as liquids, gases and plasmas. This area of research is highly important for everything from basic plumbing to aerospace engineering. Use Wolfram|Alpha to compute fluid dynamics using essential equations in the field, such as the Archimedes principle, Bernoulli's equation and the Rossiter formula.
