Scuba divers are admonished not to rise faster than their air bubbles when rising to the surface.
Question:
(a) If the viscosity of the water is 1.0 × 10−3 Pa·s, what is the terminal velocity of the bubbles?
(b) What is the largest rate of pressure change tolerable for the diver according to this rule?
Step by Step Answer:
a Use Eqs 97 916 and Newtons second law Find the terminal ve...View the full answer

In this video, the concept of pressure has been explained. The bottle is filled up with water, remove the pipe, and now you can see the clear flow of water from the holes due to liquid pressure.You can see that the second layer is holding the weight of the first layer and the third layer holding the weight of both upper layers, that’s why liquid flows out wider from the third as compared to the first two.At the first hole, water doesn’t roll along the walls; it flows out at an angle.At the second hole, you’ll see that the water flows out at a wider angle as compared to the first hole.At the third hole, we can see that the flow of water is much wider/greater than the other holes.This proves that the pressure at the bottom of the bottle is much more than the pressure at the top layers.
