As you can see in my attachment I've been directed to something I think is going to help me. I have a question. What does the p_{w} stand for? Is it power? Thanks

It should be atmospheric pressure? The water does not go all the way to the nozzle, only to a valve just before the nozzle. Thanks for pointing me in the direction of that website, looks like it's going to be a great help.

Do you mean the simple (m1)(u1)+(m2)(u2)=(m1)(v1)+(m2)(v2)? Can you show me how this would apply? I could work out the mass of the water but not it's initial velocity.

I'm afraid it drops slowly. The valve releases the pressure. The nozzle after the valve release is atmospheric pressure. I'm willing to just say that 60psi is maintained if it is easier. I will simply add it too my analysis in my lab report.

Sorry this is an experiment I carried out. I'd just like to be able to relate the pressure and the distance the water goes from the pipe. Is there information missing that you need?

What do you mean by figure?

The pipe is horizontal. I had a look at Bernoulli's equation and I had 0% of an idea how to apply to my situation.

Homework Statement I have a pipe with a capacity of 1.5 liters. Half of the pipe is filled with water and the other half air. The pressure in the pipe will be pumped to a certain value then the valve will be released. I want to determine the speed of the water as it leaves the pipe...

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.

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...
