Pressure Underwater

AI Thread Summary

To determine the depth of a vessel submerged in fresh water at a pressure of 9.42 ATM, the formula P = Po + pgh is used, where P is the total pressure, Po is the atmospheric pressure, p is the water density (1000 kg/m^3 for fresh water), and h is the depth. The atmospheric pressure at sea level is approximately 1 ATM, so the pressure due to the water column can be calculated by subtracting this from the total pressure. This results in a pressure of 8.42 ATM exerted by the water column. By rearranging the formula to solve for depth (h), the depth can be calculated using the known values. The discussion emphasizes the importance of understanding the relationship between pressure and depth in fluid mechanics.

Homework Statement

The pressure exerted on an underwater vessel is 9.42 ATM. If the vessel is in fresh water, to what depth has the vessel descended?

2. Formula

P=Po + pgh

It is fresh water so p=1000 kg/m^3

Hi cchiapuzio and welcome to the forum!
Do you know any formula that relates pressure vs depth? If yes, post it here and try to use it.

Also, what is water density?

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

Thread 'Explain this asphalt sheen'

This problem is two parts. The first is to determine what effects are being provided by each of the elements - 1) the window panes; 2) the asphalt surface. My answer to that is The second part of the problem is exactly why you get this affect. And one more spoiler:

Thread 'A cylinder connected to a hanged mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
