Some animals have learned to take advantage of the Bernoulli effect without having read a fluid mechanics book. For example, a typical prairie dog burrow contains two entrances-a flat front door and a mounded back door as shown in Fig. P3.21. When the wind blows with velocity V0 across the front door, the average velocity across the back door is greater than V0 because of the mound. Assume the air velocity across the back doo-is 1.07V0. For
a wind velocity of 6m/s, what pressure differences, p1−p2, are generated to provide a fresh airflow within the burrow?
