Who knew? Prairie dogs used the Bernoulli principle
Posted By RichC on September 24, 2022
In order to ensure sufficient oxygen within their burrow, prairie dogs use the Bernoulli’s principle. One of the entrances is built with a raised mound of dirt, while the other is not. This determines different wind velocities and different pressures. (Massimo – @Rainmaker1973)
Bernoulli flow and viscous entrainment were identified by the researchers as the processes acting on the crater mound. These create a higher velocity flow at v1, and so negative pressure gradient from one end, which draws fresher external air right through the structure.
EDIT: In a similar science and engineering vein …
The Peregrine falcon has nose cones to slow down the air coming in while diving (200 mph). The same mechanic was used for for the SR-71 blackbird and was inspired directly by the falcon! #aviationlovers #aviation #Engineering pic.twitter.com/UI7XQ3OSEs
