Need Pipe Schedule Calculation formula with available Flow rate.

What fluid? It matters!

Sludge or helium. Tell me it doesn't matter. Oh, all right then.

Fresh Water is the fluid.

I'm sure its not a straight and level (Same elevation) pipe, is there any other information that you can provide

Ya correct, Let i explain the criteria. The purpose of the question is we planned to do the hydro test in our one of tank construction site and planned to get a fresh water. Accordingly need to lay the temp pipe header lines from the buffer tank to each area by CS pipes. From there itself we planned to go with the flexible hoses for each tank. The issue is to reduce the time of operations we make a loops so we planned to fill the buffer tank minimum volume of 3000 m3 per day. It will be change as per the construction completion also. We planned with 6" 80 Sch CS pipes for Temp header lines. How ever if i know the Schedule and pipe calculation details then i can change my max Flow rate.

So, i am awaiting a Better solution in this regarding.

Hazen-Williams, Darcy-Weisbach, and Colebrook formulas, together with a Moody chart. You can Web search all of these.

Thanks for the reference.

something to do with double the flow, the pressure is squared.

In laminar flow, is flow rate proportional to pressure differential.

In but in full turbulent flow, the flow rate is proportional to the square root of pressure differential.

Yes I know. Covered in #7, now he's been pointed in the right direction OP should take it from there. But it would be highly unusual to have laminar flow on water.

I just put laminar flow in there, but the amount of information the OP provided, and one can only guess about the information that was suggested that is needed.,

Size? For a liquid, keep the velocity between 1m/s and 3m/s. If it's outside these numbers, then it is incorrectly sized. If the liquid is a non-conducting flammable then keep to the bottom end of that range to minimise the risk of static electricity building up in the fluid.

Schedule? The schedule depends upon the wetted material, the pressure, and temperature. <...water...> If the water were potable at ambient temperature, it wouldn't be going in steel pipes, so the word schedule would not be applicable. Many sewage works, for example, use thin-walled stainless steel these days whereas new buried potable pipes are almost universally laid in blue polypropylene here. So it depends upon the application, which has not been revealed to the forum.

It is usual to select the piping materials on the basis on the maximum pressure and temperature in the system. It is time to gather more information from the Process Engineer about the application and the maxima and minima of both temperature and pressure before proceeding further. In fact, this is a very necessary step that Mechanical Engineers fail to appreciate, if a statistically significant sample of the entries to CR4's Mechanical Engineering columns were to be reviewed.

Thanks. Really Helps. Also Thanx for everyone.

good math work.but, from where thickness came? simply assumed

Typical anonymous poster who doesn't know anything.

The reply clearly states "Consider this as an example".

The thickness has been considered based on schedule as per ASTM 36.10M. Hope this clarifies your doubt.

Dear Friend (anonymous

Also the Pipe Thickness can be calculated by using the Formula (p x d)/2 x t = Fs

where p = pressure in psi, d = Inner Dia of pipe in inches, t = thickness of pipe, Fs = Hoop Stress permissible for the piping material. For example, if it is MS pipe, for water mains at ambient temperature, the Hoop Stress is 12,000 psi.

You mean of course (p x d)/(2 x t). I'm sure you know, but maybe OP doesn't. Why use Fs as a symbol for stress, hoop or otherwise? Usually it's f or s.

Dear Mr. varunpassi,

Also the Pipe Thickness can be calculated by using the Formula (p x d)/2 x t = Fs

where p = pressure in psi, d = Inner Dia of pipe in inches, t = thickness of pipe, Fs = Hoop Stress permissible for the piping material. For example, if it is MS pipe, for water mains at ambient temperature, the Hoop Stress is 12,000 psi.

Thank you Mr. Dhayanandhan.
