i want to get the system curve of a pipeline , i ask about the method,i calculate th loss for fixed flow rated and i use the formula : PDC = a * (Qv^2)to get the curve. with PDC is the losshead in the system Qv is the volume flow rate when can i use yhis formula ? is there any other method ?

I'm asking about the eligibles values of the velocity in water pipeline (drinking water) (discharge pipes and aspiration pipes). I need references of these information.

I'm modeling in pipeline using AFT impulse and i want to know the difference between support "anchored upstream" , "anchored throughtout" and "with expansion joints".

i have problem of water hammer in pump station, and i want to know how to size an air vessel (analytical approach)? should i always also use a relief valve ? (this is the first time i work on this subject) Thx

i'm running a transient model of pump station, and i found that there is a vapor volume in some pipes, and i don't know how to evaluate this volume: I mean that how can i know that volume is high or it is negligeable ?! Or it shoudn't exist even ? Thx

I'm rtryinng to run a transient model of shutting off pumps with "Trip with inertia and no back flow or reverse flow" , so i can't define this junction (pump) because of efficiency values that i have entered in curve data (This error is given by The software) i didn't get the impact of...

I'm working on pump station which is already designed, But i'm want to just verify the design manually or using a software, have you any idea how shall i start?

I want to know how to dertermiate the best effciency of centrifugal pump? and the speed R.P.M at this point? Thx

i'm runing a model of pump station and i have simulated, using AFT impulse as software, the shut off of pump and the surge caused by it, so i have surge around 300 bar in upstream and downstream pipes (DN400 and DN500). i don't know if surge can reach such pressure !! I feel like i'm missing...

I hope this is the right forum. If not, please direct me to the right one. Thanks. I'm working on calculating the surge in pipe after closing a valve (Abrupt closure), and i'm confused which wave speed's formula to use. Thx

How to use the configuration option in AFT impulse software when i want to simulate various scenarios on one workspace thx
