recommended speeds for hydrocarbons

(OP)
Good Day,

I want to design a pipe for diesel but I need the recommended speed for that.

I hope you help me. Thanks

RE: recommended speeds for hydrocarbons

Do you need to do a hydraulic design, or a pressure design calculation?
Your post is too vague to even let contributors properly assist you.
Recommend you read the faq of this forum first.

RE: recommended speeds for hydrocarbons

I think you might really want the velocity rather than the speed. Search the forums on that word and you'll find some recommended values to start off with.

RE: recommended speeds for hydrocarbons

thanks for your answers, I am designing a piping, I've read the ASME B31.4, I need the diameter and I have the flow (GPM), I suppose exist a rate of velocity for diesel, gasoline or hidrocarbons in general. Could you tell me where I find that?

RE: recommended speeds for hydrocarbons

It depends on the length of pipeline and the cost of energy versus the Capex. Also you need to consider future flow rates.

RE: recommended speeds for hydrocarbons

You won't find it in any standard or specification. As a very basic GUIDE only, for long pipelines (>40 kms) start with 2 to 2.5 m / sec. Inside plants start with 4 to 5 m/ sec.

This then needs to be checked with a pressure drop calculation to determine how much pressure you need and how much power. Higher velocity means a smaller pipe, but higher power needed. Use the guide numbers above to get you a rough size and then look at options for at least one pipe size up and down from there. You may find a big difference in power requirements.

Remember pipelines are designed, not chosen by data like this and there are many many other things to consider.

Good luck.
