Good,
I thank you all (especially Snickster) for the great class on fluid mechanics.
I have always applied bernouilli for this kind of pumping problems (without an equal loop up and down) of pumping at X meters height and so on... but of course, now I had the doubt of being at the same level...
Good evening
My question is not whether it goes through a trench or overhead, but how to approach the calculation of head loss when there is an important vertical section in the system but it does not end at the top, but goes down.
If I count the head losses in pipes (valves, elbows...etc) I...
Good morning,
I have a doubt about the calculation of the installation curve for dimensioning the pump necessary to pump the fluid flow I want.
The system is as shown below, where practically the source and end tank would be at the same height, but in between, apart from the elbows, valves...
The idea I have is to be able to put for example a tank, a pump and some accessories (elbows, valves...etc) and play with the head loss to see how the flow affects it and all that (pump curve vs. installation curve).
I don't know if there is a programme that is more visual (like drawings) where...
Hello again!
Thank you very much for your comments and contributions!
Now, I have a new question (and thanks! hehe, it's always a good opportunity to learn something new).
What would happen if in the drawing I show you (pumping from an open tank to an open pipe) with the head losses in the...
Good evening, everyone,
I'm back here again for further enlightenment (greatly appreciated :))
I was reviewing the subject of pumping liquids and I had understood that at the exit of the pipe to the atmosphere (for example a tap or end of open pipe) the pressure was always the atmospheric...
Hello colleagues!
Today I'm here again to get some help with some issues I have in my head.
First of all: I hear a lot the expression ‘to clean with water with pressure on something’ and I suppose that it is not really pressure that is being talked about, but a lot of flow, isn't it? Because I...
I don't have a deep knowledge of tensions or anything like that, so it seems sensible to start learning the basics on my own with a book and then, when I have a base, maybe do a course, right?
I've seen something about Open Foam (which is open source), do you think it's a good place to start...
Good afternoon.
I am a chemical process engineer. I would like to get into the world of computational fluid mechanics (CFD) and finite element calculations (FEM).
Could you give me some advice on where I should start? Is it better to do a course and be self-taught or do a master's degree in my...
Sorry for the delay in replying, I was travelling.
I wanted to thank you all for the explanations you have given me.
I will think about it a bit more and if I have any doubts, I will comment.
Thanks again! :)
Hi all!
I would like you to help me to understand the concept of pressure in pipes where there is an incomprehensible fluid.
I imagine a pump with a pipe full of water and a valve at the outlet.
I understand the curves of the system and of the pump, to see which pump satisfies the conditions...
