This force you is because of static pressure but if you were stationary, you will experience a higher force, that is because fluid molecules hitting you will come to stop and their dynamic pressure will be converted into static pressure, thus increasing net force on you. On the other hand, dynamic pressure is the pressure that results from the motion of air, or its kinetic energy. In incompressible fluid dynamics, dynamic pressure is the quantity defined by: The simplified. As can be seen, dynamic pressure is one of the terms of Bernoulli’s equation. v 2) must increase at the expense of pressure energy (static pressure p). If there was airflow moving through a pipe, then static pressure is the pressure exerted on the walls of the pipe. In the high-velocity flow through the constriction, kinetic energy (dynamic pressure. Because any errors affecting the measurement of static pressure also affect the difference between total and static pressure, the same corrections that are applied to static pressure (for errors in the pressure delivered by the static ports) are also applied to the dynamic pressure, with reversed sign. An airplane will feel static pressure regardless of whether it is moving or not. On RAF aircraft, the measurement of dynamic pressure is made by Honeywell digital differential transducers. The dynamic pressure is equal to 0.5 times the air density times the airspeed squared, so dynamic pressure can be used to determine the airspeed of the aircraft. The difference between this measurement and the static pressure measurement (see ) is the measured dynamic pressure. In Thermodynamics, pressure is defined in a bevy of ways. ![]() The total pressure, the sum of ambient and dynamic pressure, is normally sensed using a pitot tube, a tube pointed in the direction of the relative airflow and specially designed to be relatively insensitive to small-angle changes in the direction of the relative airflow. The dynamic pressure is the excess pressure above ambient that develops when air is compressed and adiabatically brought to rest relative to the moving aircraft. ![]()
