Fluid dynamics, including mechanics of liquids and of gases, is a part of physics. We can divide the processes of any physical theory into four steps:
  1. 1.

    Placing observed data into general physical laws, assuming the uniformity of nature.

  2. 2.

    Transferring the physical laws into mathematical form, thus obtaining a logically consistent system of axioms which usually consists of a system of differential equations.

  3. 3.

    Drawing conclusions from these differential equations. This is a purely mathematical step.

  4. 4.

    Check on the results obtained in (3) by experiments.
