FLUIDS-how far from dam base does stram hit ground

In summary, the conversation discusses using Bernoulli's equation to find the distance from the base of a dam to where a stream hits the ground, given the height of the dam and the location of a hole halfway down. Additionally, it mentions using the same equation to determine the distance a thrown ball will travel, requiring knowledge of velocity and distance.

Homework Statement



a dam of height H has a hole half way down to the base. how far outward from the base does the stream hit the ground?


Homework Equations





The Attempt at a Solution


i think you have to use bernoulli's equation right?
first find velocity then distance x right?

Assume that the fluid is just a ball. If someone throws a ball from an elevated location, what information must be known in order to determine how far he throws it?

FAQ: FLUIDS-how far from dam base does stram hit ground

What are fluids?

Fluids are substances that can flow and take on the shape of their container. Some common examples of fluids include water, oil, and air.

How far from the dam base does a stream hit the ground?

The distance from the dam base to where the stream hits the ground will depend on various factors such as the height of the dam, the velocity of the stream, and the angle at which the stream is released from the dam. Additionally, the topography of the surrounding area can also affect the distance. A more accurate determination of this distance would require a detailed analysis of these factors.

How does the shape of a dam affect the distance of the stream from the base?

The shape of a dam can play a significant role in determining the distance of the stream from the base. A curved or arched dam can create a longer path for the stream to travel, resulting in a greater distance from the base. On the other hand, a straight or angled dam may allow the stream to hit the ground closer to the base.

Can the velocity of the stream be altered to change the distance from the base?

Yes, the velocity of the stream can be altered to change the distance from the base. Increasing the velocity of the stream can result in a longer distance from the base, while decreasing the velocity can bring the stream closer to the base. However, this change in distance will also depend on the other factors mentioned above.

How do topographical features impact the distance of the stream from the base?

Topographical features such as hills, valleys, and other obstructions can affect the distance of the stream from the base. These features can either allow the stream to travel a longer distance before hitting the ground, or they can block the stream and cause it to hit the ground closer to the base. The specific impact will depend on the location and layout of these features in relation to the dam.
