Part 1: A simplified model of how an airplane flies relies on a difference in air pressure between the top and the bottom of the wing. If a Boeing 737 has a mass of 46,700 kg and a total wing area of 104 m2, what difference in pressure (in N/m2) is necessary for the airplane to maintain altitude? Part 2: In contrast to the previous question, calculate the pressure difference (in N/m2) necessary for a 105 g Sharp-shinned hawk with a wing area of 0.04 m2 to maintain altitude.
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.
