hydrodynamic pressure

hydrodynamic pressure

[‚hī·drō·dī′nam·ik ′presh·ər]
(fluid mechanics)
The difference between the pressure of a fluid and the hydrostatic pressure; this concept is useful chiefly in problems of the steady flow of an incompressible fluid in which the hydrostatic pressure is constant for a given elevation (as when the fluid is bounded above by a rigid plate), so that the external force field (gravity) may be eliminated from the problem.
