How can fresh air flow in a prairie dog's burrow?

Best Answers

Prairie dogs build one entrance of their tunnel higher than the other because the wind speed is higher with increasing altitude. read more

So the entrance with high velocity air flowing above it will have lower pressure as opposed to the other end at lower altitude with lower velocity. This slight pressure difference causes the air to flow through the burrow as shown in the diagram. read more

The way that a prairie dog builds the openings to its burrow, however, helps to harness wind energy from the windy plains and create passive ventilation through the burrow’s tunnels. As air flows across a surface, a gradient in flow speed forms, where air moves slower the closer it is to the surface. read more

Prairie dogs build one entrance of their tunnel higher than the other because the wind speed is higher with increasing altitude. Here Bernoulli's principle comes into play,according to this principle, the lateral pressure exerted by a fluid stream decreases as the speed of the stream increases, and vice versa. read more
