Pressure exerted by a fluid in a closed container

Click For Summary
SUMMARY

The discussion centers on the behavior of water flow from a hole in a closed container when subjected to free fall. Participants concluded that in a free-falling scenario, the water would not flow out as it would under normal gravitational conditions. This is due to the absence of relative gravitational force acting on the water, resulting in a weightless environment. The analogy of a baseball in a freely falling elevator illustrates that objects do not fall relative to the container, leading to the cessation of water flow.

When a hole is made in the side of the container holding water, water flows out and follows a parabolic trajectory. If the container is dropped in free fall, what will happen to the water flow?

I think that the water flow will follow a similar trajectory..what effect can gravity have on it?
it will still exert pressure on the walls of the container and therefore will come out. What can be the change?
Am i correct?

Imagine that you are in a freely falling elevator. In such a situation, if you let go of a baseball from your hand, do you expect that it would drop to the floor?

yes it will drop.
 
The surprising thing is that, no, it wouldn't! Everything would become as if weightless. You would let go of the ball and it would just float there.

yeah so you mean that we will be traveling at the same rate as the ball does, and we won't see it falling down. Then connecting it to the original question says that the flow of water will stop?
 
Right.
 
Thanks. Actually i thought on the same line but got confused.
