You're absolutely right, this is just a situation where because it was obvious to me (since I know I'll have it open to atmosphere), I failed to mention it in my post. The original post should have mentioned that the initial pressure of the air is known as well.
Given these knowns, I need help...
The air in the tank is at atmospheric pressure to begin. It actually opens to the atmosphere first before the top of the tank submerges, but I'm overly generalizing the problem to get a better understanding of what's going on here.
Being a rather novice engineer, I'm having trouble coming up with a solution to this problem. I think it's a rather simple problem with just a slightly complex twist (unsteady flow).
There's a tank submerged in water a certain depth (pictured). The tank has a known volume and contain a known...
Alright, thanks, I'll give it a try. The problem is I just can't visualize what orbits look like if I have to account for a moving frame of reference as well. Everything changes. I don't quite see how to encorporate it into any equation, either.
But I'll see what I can do. The amount of help...
Homework Statement
There is a planet of mass m_1 orbiting a star of mass m_2. One question is "What is the semimajor axis of the planet's orbit in the coordinate system centered at the star's center", and another is "What is the semimajor axis of the planet's orbit centered at the center of...
