An airplane wing is designed so that the speed of the air across the top of the wing is 250 m/s when the speed of the air below the wing is 225 m/s. What is the difference in pressure (AP=P2 - P1) below and above the wing? Assume that the difference in height between the top and bottom of the wing is negligible. The density of the air is 1.29 kg/m³ 7.66 x 10³ Pa 280 x 10³ Pa 1.58 x 10³ Pa 2.59 x 104 Pa
Fluid Pressure
The term fluid pressure is coined as, the measurement of the force per unit area of a given surface of a closed container. It is a branch of physics that helps to study the properties of fluid under various conditions of force.
Gauge Pressure
Pressure is the physical force acting per unit area on a body; the applied force is perpendicular to the surface of the object per unit area. The air around us at sea level exerts a pressure (atmospheric pressure) of about 14.7 psi but this doesn’t seem to bother anyone as the bodily fluids are constantly pushing outwards with the same force but if one swims down into the ocean a few feet below the surface one can notice the difference, there is increased pressure on the eardrum, this is due to an increase in hydrostatic pressure.
