Question
Prairie dogs are burrowing rodents. They do not suffocate in their burrows, because the effect of air speed on pressure creates sufficient air circulation. The animals maintain a difference in the shapes of two entrances to the burrow, and because of this difference, the air (ρ = 1.29 kg/m3) blows past the openings at different speeds, as the drawing indicates. Assuming that the openings are at the same vertical level, find the difference in air pressure between the openings.
Transcribed Image Text:In this illustration, we observe an underground burrow system with complex tunnels. Situated above the surface are three animals. Two red arrows indicate air velocities at different points in the system:
- The arrow on the left shows a velocity of \(v_A = 8.5 \, \text{m/s}\).
- The arrow on the right indicates a velocity of \(v_B = 1.1 \, \text{m/s}\).
This setup likely represents a study of airflow dynamics in burrow systems, possibly focusing on how wind speed varies at different entry and exit points, affecting ventilation and environmental conditions within the habitat.
