Dynamic pressure from speed¶
Dynamic pressure, sometimes called velocity pressure, is a physical quantity denoting the pressure caused by a flowing fluid. It is numerically equal to the kinetic energy of the fluid per unit volume (see Quantity is volumetric density times volume).
Notes:
Many authors define this quantity only for incompressible flows, but others extend it for compressible flows as well.
