I'll be the first to admit I know little to nothing about fluid dynamics, especially in a pressure vessel. I was wondering how pressurized rocket fuel tanks don't cause weight-distribution problems when they begin to tilt, or do they?
This is what I was thinking through basic observations:
- I have a water bottle in my hand, it is full.
- If I flip this bottle in the air it will flip uniformly.
- I drink half the water in the bottle and flip it again.
- On the first half rotation, the liquid sloshes to the other side.
- This force causes the rotation to not be uniform.
However, with a pressurized can of aerosol or liquid:
- I flip the can when it's full.
- It flips uniformly.
- I flip the can when it's half-empty.
It flips uniformly.- According to @Uwe my assumption is false, however at a small scale like this the "slosh" may not be obvious.
This may be more of a physics question at this point, but why does it work like that? Does it?
I guess the main questions after my random rambling would be:
Can someone explain the potential problems with sloshing for different types of fuels, 1 pressurized example and 1 non-pressurized example would be great to show how a pressurized vessel would "slosh"? Maybe a diagram would help me understand better.
