Where Is Water Pressure Greatest in Water Propulsion Systems?

[usmarine]

water propulsion? whoosh!

I've seen this question written three different ways and each gives three different answers. I'm just not sure how the answer is gotten.



Here is what I see when I see the question...either two straight lines to depict a pipe for water, or a straight line and a line that shows a dip to depict a pipe.

Then, the question goes something like, where is the water pressure the greatest? It turns out, that no matter what I choose, I'm wrong every time I answer the question.

It turns out that there are different ways of describing where water pressure is entering or exiting the pipe so I'm constantly getting the question wrong. Is there some way to identify where, point A (the entrance of the pipe), B (the middle of the pipe), or C (the exit of the pipe) where the most pressure is going to be depending on how the question will be written?

The answer to this question depends on the type of propulsion system being used. Different types of propulsion systems will produce different levels of pressure at each point. For example, in a jet propulsion system, the pressure would be greatest at point C (the exit of the pipe). However, in a propeller-based system, the pressure would be greatest at point B (the middle of the pipe). Therefore, it is impossible to provide one definitive answer to this question without knowing more information about the type of propulsion system being used.

I can understand your confusion and frustration with the different ways the question is presented. However, the concept of water propulsion remains the same regardless of how the question is written. Water propulsion refers to the use of water as a propelling force, typically in the form of a jet or stream, to move an object or vehicle. This is commonly seen in water sports such as jet skiing or in the propulsion systems of boats and submarines. The pressure of the water being forced out of the pipe or nozzle is what creates the propelling force. So, in terms of the question, the water pressure will be greatest at the point where it is being forced out of the pipe or nozzle, regardless of whether it is at point A, B, or C. The key is to understand the concept behind water propulsion and how it works, rather than getting caught up in the different ways the question is presented.
