AI Thread Summary
To determine the exit velocity of water from a pipe, the user has gathered data including pressure in the pipe (60 psi), nozzle diameter (3mm), and atmospheric pressure. They are considering using Bernoulli's equation but are struggling with the concepts of static and stagnation pressure, as well as dynamic pressure. The user attempted to apply relevant equations but found them confusing and is unsure how to measure dynamic pressure experimentally. They are contemplating measuring distances and times for the water flow as an alternative method. The discussion highlights the challenges of applying theoretical equations to practical experiments in fluid dynamics.

Homework Statement


Hi

I have constructed a pipe with a pressure gauge and a valve. I know the pressure of the air and water in the pipe. I know atmospheric pressure and I know the nozzle size. I want to be able to find the velocity of the water leaving the pipe.

Here are some variable I have:

1.)Pressure in pipe: (Static Pressure? I'm not sure about how to differentiate to stagnation pressure) (60psi)

2.) Nozzle diameter (3mm) , Pipe Diameter (15mm)

3.) Atmospheric Pressure (sea level)




Homework Equations



There is no set way to do this as it's a project of my own choice but after research I know that perhaps Bernoulli's equation may be relevant.

Another q=1/2P_{s}M^{2} γ Which I think may be useful.

The Attempt at a Solution



After trying to use Bernoulli's equation and failing for many hours I gave up. I didn't understand the constant.

When trying to apply the second equation to my experiment I found that the dynamic pressure part was confusing me. I didn't know how this related to my experiment and by defining it online I didn't see how it could be obtained experimentally. Seeing as it's defined by it's velocity and that's what I'm trying to find out?

I was thinking about simply creating some distances and time results for the water and using those.

Does anyone know a different approach to this? I've been at it for a long time and can't think of a way to do it apart from those two equations.
 
Thread 'Struggling to make relation between elastic force and height'
Hello guys this is what I tried so far. I used the UTS to calculate the force it needs when the rope tears. My idea was to make a relationship/ function that would give me the force depending on height. Yeah i couldnt find a way to solve it. I also thought about how I could use hooks law (how it was given to me in my script) with the thought of instead of having two part of a rope id have one singular rope from the middle to the top where I could find the difference in height. But the...
Thread 'Voltmeter readings for this circuit with switches'
TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...
