Who knew? Prairie dogs used the Bernoulli principle

Posted By on September 24, 2022

Prairie_Dog_WasIn 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 …


Desultory - des-uhl-tawr-ee, -tohr-ee

  1. lacking in consistency, constancy, or visible order, disconnected; fitful: desultory conversation.
  2. digressing from or unconnected with the main subject; random: a desultory remark.
