I want to cut the graph in two. And yeah, the integral of the left piece should be equal the integral of the right. I think I solved it and got 2/3 b^3 = 1/3 c^3. This is if I take the integral from 0 to c, then b will be the center. I was wondering if this works as a general solution?

Hello, If I have an x^2 graph that goes from 0 to a point a. Is there a general solution to where the area of the left side is equal to the area of the right?

I am familiar with each part of the equation, but I have never solved it iteratively. I'll try to solve it and post the results. Thank you for the help.

Sorry for taking so long to respond. The hydroplant design considerations contain a lot of the information I was looking for, thank you. I haven't finished it yet, but so far it's good. Where did you find it? Any suggestion of where I should start when looking for reports like these? I...

My problem is that I do not know at what speed the flow will become steady. If i have an infinite water reservoir and a pipe empty of water. If I let water into the pipe and let water run through until it reaches a stable velocity. What is the velocity?

I can't assume the flow rate. What are the design factors that control the flow rate in a tube?

I will try to provide a sketch when i can get a hold of a scanner. The relevance is 1) to determine the pressure loss in the pipe which is mostly dependent on the steady flow velocity in the pipe. 2) to choose the exit nozzle diameter to get the optimal exit velocity.

I have calculated major and minor losses in the pipe with an assumed flow rate. Used Reynolds number, friction factor, Moody diagram and geometric coefficients.

Yes. I am guessing that the terminal velocity will be a product of gravity pulling the water down, and the walls and viscosity counteracting this. That will be gravity versus drag. I am writing a bachelor thesis about designing a hydro power plant and have completed 1 bachelor level course in...

In my problem I have a tube at an incline, empty of water. I then open a gate letting the water flow into the pipe. All design parameters like cross sections, length, incline are all known. I wish to know what is the velocity of the water when it is fully developed?

Hello, How do you calculate the terminal velocity of a fluid through a pipe. My problem includes turbulent flow, very high reynold number, and water (incompresible).

Sounds like a bad way to go. Thanks for explaining.

Because water stick to surfaces making it very hard to escape the water surrounding you? Like the Canadian astronaut pouring water on his eyes to simulate crying in space.

Is swimming affected by gravity? How will swimming in micro gravity compare to high gravity and low gravity.

Is it possible for planets to have multiple liquid layers? Like a ocean made of water, with an ocean within, consisting of a heavier liquid. And could it have a sirculation, as water does on Earth?
