Calculating GRP pipe diameter
Calculating GRP pipe diameter
(OP)
Hi all,
Could you please advise how I can calculate GRP pipe diameter?
I have application submersible pump for sewage water, flow rate 200 L/S, pressure is 10 bars, Pipe line length is 200 meters.
Thanks in advanc,
Baram

RE: Calculating GRP pipe diameter
See what kind of answers ambiguous questions yield? Are you wanting to know the ID for a given OD of a specified grade of pipe? Are you wanting to know predict what ID would give you a specific pressure drop (or velocity)? Are you trying to find the nominal pipe size for a given ID?

Nominal Pipe Size (NPS) = inside diameter (ID)
The reason for this is because it is "layed-up" on a mandrel layer by layer. The more layers the thicker the pipe wall and the more pressure the pipe can carry.
At least that is what I remember from when I did my last project with FRP pipe.

You have a flow rate of water to get through a certain length of pipe. The size of pipe will determine how much pressure drop is required to get that flow of water through the length. It's going to make a difference if you can accept 1 bar pressure drop through that 200m of piping or if you can only accept 0.1 bar pressure drop through that piping.

We know a flow rate, a pump discharge pressure, and a length. If we knew what your goal was someone here could probably help. You want "nominal pipe diameter" for what? Are you trying to deliver your flow rate into atmospheric pressure or 9 bar or 2 bar? It matters. Why don't you take a minuted and tell us what you're trying to accomplish and someone may be able to help.

I mentioned that application is sewage water also the pressure is 10 bars, should calculate 1 bars losses because of elevations , if you need something else, please let me know.

Flow (gpm) *.3208 / area^2 (inches) = velocity (ft/s)
