Pressure loss calculation in Pipeline
Pressure loss calculation in Pipeline
(OP)
Dear All
After reviewed several threads talking about pressure loss calculation in pipeline (all type of fluids; compressible, incompressible etc.), I would like you to share your partical and competent experiences in this matter.
My first question is whether or not there are any recommended technical documents,books or guildlines summarized formulae, equations or even techniques.
Another question is there is an effective software that you guys use for calculating the pressure drop in certain systems?. since it will take a lot time to calculate or revise some complex systems (lots of fittings, valves, equipment) Please do not feel this is a commercial issue, coz there are numerous softwares in the market now andI am not sure that which one has a correct outcomes or results regardless of human error input.
For both questions, I just want to know which one(s) you would recommend from your experience.
Thank a lot in advance for your recommendations or suggestions
Best Regards,

Flowmaster: Good for both gas and liquid phases. Gas is very slow in long trancient pipeline especially with abrubt changes in flow (e.g. simulation of a leak). Very good for simulation plants with valves changing operating conditions etc.
Pipeline studio: Very fast and very good for pipelines. Not so suited for plants.
HYSYS (And other process simulation tools). Very strong in thermodynamics. Is ususally only suited for "one string" lines since they normally cant handle a "distributed" network (it will at least take a lot of manual "help").

For water systems, Bell and Gossett has many good manuals as well. See there website http://www.bellgossett.com/
I'm sure there are many others but these two sources have a great deal of information.

Hi. krb
I have a technical document of Crane valve you mentioned in the hand rignt now but i don't feel comfortable to use it sometimes. Since, as i said, it will take a lot of time to find centain values of friction coefficient (K) for several fittings espectially. Perharps i have no enough patience to use this manual but thanks for your confirmation anyway. I'll make more try on this.
Any further? please let me know, thanks so much
Regards

Also the need for multiphase or not. If you are interested in multiphase then you must know something about the models etc. I havnt got any expeirence in modelling slurries. I dont think any of the programs that i just mentioned can handle slurries as anything else but a viscous fluid?
Best regards

Has anyone else checked to see how the programs they are using calculates K values?

The more you learn, the less you are certain of.

Then select pressure drop. Provides some easy to use calculations and provides Re, fricion factors delta p etc.

I am a user of these programs and also assist with Beta testing. I have used other programs such as Haestad Watercad and SewerCad, Epanet etc. AFT's products are well proven and robust. The support is second to none as you deal with real piping engineers not computer scientists.

Software for pipeline pressure drops for single or multiphase fluids :
- Pipesim / Pipesim-Net Steady State [Schlumberger]
- Olga Transient multiphase [Scandpower]
- Flowmaster single phase transient
- Pipeflow steady state [neotech]
- Pipephase Steady State [Simsci]

You need a really steady hand on the mouse, or everytime you select a pipe segment, it goes a bit squiggly. I hate that. I don't have a super steady hand. Maybe it's my mouse...
Other than that, it works really well.
