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. P3.20. 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 door is 1.07 V₀. For a wind velocity of 6 m/s, what pressure differences, p₁-p₂, are generated to provide a fresh airflow within the burrow?
