Exponantial contraction in fluid systems

[tifoso]

Hi,

I am trying to find a exponantial variation in the pipe crosssection. Crosssection area must be decereased in an exponantial behaviour. Is there a formula for that. If there is how can I find it.

Thanks

Are you talking about thermal expansion of a fluid?

 

[tifoso]

No, I looking a formula that describes the shape of the pipe. Pipe crossection decreases or contracts in an exponential behaviour. Or transition between large pipe and small pipe must be governed by an exponential formula. How ca I find that.

Stop looking for that and start looking for a mistake in the specification. Sounds like some computer program did the translation.

Ooh er Titsoso .... dummy and toys flying out of the pram there !

Pipe diameter transitions may be conical or belled/concavo-convex, but their exact shape is governed by forming limitations, not by equations.

I.e., your question, viewed from our end of the Translation Tunnel, seemed a little bit silly.

Therefore Big's response was entirely appropriate, and constructive.

Crane's Technical Paper 410 "Flow of Fluids" might be of help if you're wanting formulas to size piping (though I'm not exactly sure what is meant by "Cross-section area must be decereased in an exponantial behaviour." Why MUST it be decreased exponentially?)
