You are designing a diving bell to withstand the pressure of seawater at a depth of 250
Question:
(a) What is the gauge pressure at this depth? (You can ignore changes in the density of the water with depth.)
(b) At this depth, what is the net force due to the water outside and the air inside the bell on a circular glass window 30.0 cm in diameter if the pressure inside the diving bell equals the pressure at the surface of the water? (You can ignore the small variation of pressure over the surface of the window.)
Step by Step 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.
