Race car down force. Modern race cars come with a variety of airfoils to help hold them on the track, especially in flat turns where the cars tend to slide out of the turn. Another technique involves channeling air through an opening in the front of the car, down under the car's body, and then out behind the car. The air effectively flows through a pipe that is narrow in one section (the space below the car). Suppose the front opening has area A₁ = 0.75 m² and the space between the track and the bottom of the car has an area of A, = 0.15 m². If the car is moving at speed v = 240 km/h and the pressure above the car is 1.0 atm, approximately what is the pressure difference (in atmospheres) between the top and bottom of the car, pushing down on the car?

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.
