Dynamic pressure from speed
===========================

**Dynamic pressure**, sometimes called **velocity pressure**, is a physical quantity denoting the
pressure caused by a flowing fluid.

**Notes:**

#. Many authors define this quantity only for *incompressible flows*, but others extend it for
   compressible flows as well.
