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?

Concept explainers

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.

Question

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 A₁, = 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?

A frequently quoted rule of thumb in aircraft design is that wings should produce about 1000 N of lift per square meter of wing. (The fact that a wing has a top and bottom surface does not double its area.) a. At takeoff, an aircraft travels at 55 m/s, so that the air speed relative to the bottom of the wing is 55 m/s. Given the sea level density of air to be 1.29 kg/m3, how fast must it move over the upper surface to create the ideal lift? b. How fast must air move over the upper surface at a cruising speed of 249 m/s and at an altitude where air density is one-fourth that at sea level?
> Question 4 of 8 > © Macmillan Learning A 0.573 kg metal cylinder is placed inside the top of a plastic tube, the lower end of which is sealed off by an adjustable plunger. The cylinder comes to rest some distance above the plunger. The plastic tube has an inner radius of 5.37 mm and is frictionless. Neither the plunger nor the metal cylinder allow any air to flow around them. If the plunger is suddenly pushed upwards, increasing the pressure between the plunger and the metal cylinder by a factor of 2.31, what is the initial acceleration a of the metal cylinder? Assume the pressure outside of the tube is 1.00 atm and that the top of the tube is open to the air. a = 27.29 Incorrect m/s² 100 > Attempt 3
