Chapter 10, Problem 18Q

To determine

To Explain: The concept of canvas top of a convertible bulge out when the car is traveling at high speed.

Explanation of Solution

Introduction:

Bernoulli’s Principle- According to this principle, there is a pressure difference which results in a force that causes the bulging of top outwards.

According to Bernoulli’s Principle, higher the air speed, the lower the pressure will be. The air in the car is motionless whereas the speed of the air outside the car is higher. Due to this the pressure inside the car is atmospheric pressure and outside the car the pressure is low. Because of the pressure difference inside and outside the car, the canvas top is pushed away or the convertible bulges out.

Conclusion:

By the Bernoulli’s principle, it can be concluded that there is a pressure difference which results in a force that causes bulging of the top outward. The windshield deflects air upward, pushing streamlines closely.
