Pressure exerted by a fluid in a closed container

In summary, when a container holding water is dropped in free fall, the water will still flow out due to gravity exerting pressure on the walls of the container. However, in a freely falling elevator, objects will appear weightless and will not drop to the floor. This means that the flow of water will also stop in this situation.

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.
 

Related to Pressure exerted by a fluid in a closed container

What is "pressure exerted by a fluid in a closed container"?

"Pressure exerted by a fluid in a closed container" refers to the force per unit area that a fluid exerts on the walls of a closed container. This pressure is caused by the molecules of the fluid colliding with each other and with the walls of the container.

How is pressure exerted by a fluid in a closed container measured?

Pressure is typically measured in units of force per unit area, such as pounds per square inch (psi) or pascals (Pa). To measure the pressure exerted by a fluid in a closed container, a pressure gauge or sensor can be used to measure the force exerted by the fluid on a given area of the container's walls.

What factors affect the pressure exerted by a fluid in a closed container?

The pressure exerted by a fluid in a closed container is affected by several factors, including the density and temperature of the fluid, the volume of the container, and the force of gravity acting on the fluid.

How does the pressure exerted by a fluid in a closed container change with depth?

In a closed container, the pressure exerted by a fluid increases with depth. This is due to the weight of the fluid above pushing down on the molecules below, increasing the number of collisions and therefore the pressure exerted on the walls of the container.

What are some real-world applications of pressure exerted by a fluid in a closed container?

Understanding pressure exerted by a fluid in a closed container is important in many fields, such as engineering, meteorology, and medicine. It is used in the design and operation of hydraulic systems, weather forecasting, and blood pressure monitoring, among others.
