An airplane is in level flight at low altitude, so that atmospheric pressure and densities are 1 atm and 1kg/m3 , respectively. There is a pitot tube attached to the airplane, so that air entering the tube stagnates at the rear of the tube. The stagnation pressure is measured to be 1.45x105 Pa. What is the speed of the airplane? (The laser is there to detect particulates in the air which might interfere with the operation of the probe).
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.
