Pressure Loss Calculation for Water Pipeline

Priceless - GA

i now the compressor air pipe pressure lose calculation method but also i no hydraulic calculation but i am not work on that that's way i am asking .

Thanks

Go to the Globalspec that hosts CR4. They feature a number of flow/pressure drop calculation programs such as Hazen-Williams.

My post at #1 was somewhat tongue-in-cheek (playful).

We seem to have a bit of a communication problem. Did you get anywhere in the thread with srijitpv (http://cr4.globalspec.com/member?u=14371) ? Perhaps he/she might be willing to chat by PM - you possibly speak the same language, and might be able to help you clarify the question.

Another possibility is to detail a problem that matches the one you are trying to understand/solve. Some numbers or drawings would help clarify.

Although it didn't appear to demonstrate calculations, the software suggested by Sandman looks to be very good in terms of deriving a solution for some situations. What specific situation(s) are you looking at ?

If it's any consolation, your English is a lot better than my ability would be in your 1st language

The information and tables at pages 15-21 through 15-24 at http://www.acipco.com/international/products/Sec15.pdf for metric sized or similar for inch-sized pipe at http://www.acipco.com/adip/products/Sect17.pdf may be of help.

Hey Srin -

If you are interested in a pumped circuit, and can use simple graphic drag-and-drop software to model the pipe sizing and head loss, this may be an option. We have found no easier to use free tool for Mechanical Engineering for closed-loop systems than the hydronic-only version of "HVAC Solution." I use the 'Pro' (version 5.0 now) for diagramatic analysis of HVAC systems when a full 3D BIM design is not required - and often as a backup check even when attempting a Revit model, as the diagram and Bill of Materials and the auto-created Excel spreadsheet are such easy tools for review of the design.

The free (limited to hydronic fluids) version is hosted by the TACO pump company, and can be downloaded here: Hydronic System SolutionThe

The "help" functions also have very well done explanations of the calculation and modelling methods, and there are video tutorials on the main website that are free downloads as well.
