The empirical evidence for Bernoulli’s effect.
Answer to Problem 1RQ
Solution:
Snoring while sleeping is an empirical evidence of Bernoulli’s effect.
Explanation of Solution
Introduction:
Bernoulli’s principle states that fluids moving at a faster velocity have lesser pressure (In general, fluids include both liquids and gases. Air is a gas; hence, it is classified as a fluid). This falling of pressure due to increase in the velocity of a fluid is known as Bernoulli’s effect.
Explanation:
When air moves through the narrow opening above the soft palate at the back of the upper portion of the mouth, its pressure decreases. Below this soft palate, stationary air is present that exerts higher pressure on the palate. Due to this pressure difference, the palate is pushed and the opening tends to close.
The palate retakes its position when airflow stops, resulting in the opening of the passage. This phenomenon keeps on repeating. The opening and closing of the palate forms a rhythm. The palate vibrates with a rhythmic movement due to the continuous airflow, which leads to snoring.
A diagram representing the situation is given below.
Conclusion:
Snoring while sleeping is an empirical evidence of Bernoulli’s effect.

- The alveoli in emphysema victims are damaged and effectively form larger sacs. Construct a problem in which you calculate the loss of pressure due to surface tension in the alveoli because of their larger average diameters. (Part of the lung's ability to expel air results from pressure created by surface tension in the alveoli.) Among the things to consider are the normal surface tension of the fluid lining the alveoli, the average alveolar radius in normal individuals and its average in emphysema sufferers.arrow_forwardFigure 11.35(a) shows the effect of tube radius on the height to which capillary action can raise a fluid.
