Prairie dogs are burrowing rodents. They do not suff ocate
Chapter , Problem 61(choose chapter or problem)
Prairie dogs are burrowing rodents. They do not suff ocate in their burrows, because the eff ect of air speed on pressure creates suffi cient air circulation. The animals maintain a diff erence in the shapes of two entrances to the burrow, and because of this diff erence, the air (r 5 1.29 kg/m3 ) blows past the openings at diff erent speeds, as the drawing indicates. Assuming that the openings are at the same vertical level, fi nd the diff erence in air pressure between the openings and indicate which way the air circulates.
