I found that ##Y = \frac{1}{2} \frac{\omega ^2}{g} R^2 ##. If the pressure at the hole is ## \delta g (H+Y) ##, then using Bernoulli's equation in the hole and the center of the water surface gives me: ## \delta g (H+Y) + \frac{1}{2} \delta v_{r}^2 = P_{atm} + \delta g H ##. So ##v_{r} =...

I think I understand most of your reasoning, but I'm not sure about how I could obtain Y in terms of the given data. Also, wouldn't the pressure at the hole be Patm, since it's exposed to the exterior of the tank? Without obtaining Y in terms of the other quantities and assuming the pressure at...

We have a cylindrical water tank that spins over its axis of symmetry with constant angular velocity ω. Here's a diagram: We wish to find: 1 - The tangential and radial components of the velocity of the water as it leaves the tank. 2 - The radius r reached by the water. I'm not sure at all...

I haven't learned absolutely anything about relativity yet, and I'm don't know what that convention you're talking about is. Would you say I shouldn't learn relativity from this book? Even then, are the other parts good enough on the first edition, or should I buy the new one?

Well, I wasn't expecting that. Why is the first one better? All I've noticed is that the second one seems to have more exercises.

I have access to a copy of the first edition and would like to use this book to strengthen what I've learned in my first physics course in Engineering school. I know there is a second edition though, and I was wondering if the difference between the two is large enough to justify just buying...
