- The static pressure is the pressure that would be measured at the given point in the fluid if the fluid were not moving. The dynamic pressure is the difference between the total pressure—that is, the pressure you would actually measure at the given point in the moving fluid, with some appropriate instrument—and the static pressure.

For incompressible flow, the dynamic pressure of a fluid is the difference between its total pressure and static pressure. From Bernoulli's law, dynamic pressure is given by = where p 0 and p s are the total and static pressures, respectively.
Hydrostatic pressure arises due to the weight of a fluid acting on an object. Hydrodynamic pressure arises due to a fluid moving against an object and any pressure gradient in the system. These two pressures will occur together in real flows.

There are two ways to look at pressure: (1) the small-scale action of individual air molecules or (2) the large-scale action of a large number of molecules. On the small scale, from the kinetic theory of gases, a gas is composed of a large number of molecules that are very small relative to the distance between molecules. The molecules of a gas are...
To understand dynamic pressure, we begin with a one-dimensional version of the conservation of linear momentum for a fluid. \LARGE \rho u \frac{du}{dx} = \frac{-dp}{dx} where \rho is the density of the gas, p is the pressure, x is the direction of the flow, and u is the velocity in the x-direction. Performing a little algebra: \LARGE \frac{dp}{dx} ...
The dynamic pressure is a defined property of a moving flow of gas. We have performed this simple derivation to determine the form of the dynamic pressure, but we can use and apply the idea of dynamic pressure in much more complex flows, like compressible flows or viscous flows. In particular, the aerodynamic forces acting on an object as it moves ...
Feb 17, 2015 · Under common assumptions and ignoring potential energy, static pressure is the expression of the fluid's temperature (internal energy) and dynamic pressure is the expression off the fluid's velocity, so if the fluid is brought to a rest adiabatically, their sum is equal to the stagnation pressure.
The dynamic pressure is the difference between the total pressure—that is, the pressure you would actually measure at the given point in the moving fluid, with some appropriate instrument—and the static pressure. The dynamic pressure is the part of the pressure that is associated with the motion of the fluid. There will be much more
Hydrostatic pressure is a fundamental concept in physics that is based on the idea that a fluid at rest exerts downward pressure due to the column of fluid above a specific point. Its formula and illustrative examples demonstrate how it is calculated and how it affects objects immersed in a fluid.
