tube diameter

[Il marangon]

hello to all

I press that my tire and related knowledge is 0 for which I don't know where to smear the head

As the recovery is coming we are reorganizing the workshop and among the various things to do we must move 2 pumps of the vacuum from 250 mc2/h.
Currently from these comes a rubber tube 6 m long for about ø50 (inside) about. the pumps, once relocated they will have about 30 mt of pipe.
Now my doubt is that increasing the length of the tube may have load losses so the size of the pipe will also be modified, right? what diameter should I use on the new plant?

greetings and thanks

hello surely you will have losses that if I am not mistaken are proportional to the square of the flow. depend on the length of the pipe and also other parameters such as pipe, material and pipe scabrocity, also you must also consider concentrated type leaks if you have :valves, fittings, curves
I think you should make a layout of the plant trying to establish what you need, i.e. flow rate, pressure at the end of your 30 m, predict the spin that you will make the tube with all the various valves and fittings and finally dimension everything for a minimum loss.
up www.oppo.it you can find some calculations and explanations for what concerns water pipes and related load losses, for the air you have to take into account that it is "fluid" compressible and therefore you will also have the density variation .
I hope I haven't told you too many chestnuts and I've been helpful
Hello Michael

I think I don't come out alone.

If it were a vacuum tube with an average velocity of the known air and a constant flow perhaps I would come to the head but with vacuum pumps that must suck all the suckable? Where to go?

missing information to give you advice.
what type of pumps you use
you have to do
What are you doing?
It's better to use armed plastic pipes
every 6/7m there is a parabolic fall of the vacuum limit of the pump:certain that increasing the section of the tube you can go further, but the times can be extended even much.
Good evening.
