Hi all,
I am looking for information regarding pressure drop calculation of two-phase fluid in an elevated pipe.

I found that Beggs and Brill correlation is a common practice.

Request: I need correlations for pressure drop due to:
1. friction
2. accelration
3. static head
For a straight pipe, i think the total pressure drop = pressure drop due to (1+3)

Thanks
Suresh

Hi Suresh
I sent by e-mail the information I promissed

If you don´t receives, please tell me for look alternate way for sending.

The file is abour 6 Mb. in acrobat.

Good luck

Hi, Profe

I can see that ur online,

Will u send me the same file u sent to Mr, suresh....

I am also one of the interested candidate to learn two phase phenomena

Email: jetul@rediffmail.com

thanks

bye

Suresh,
I need to take issue with one statement you made earlier. The acceleration losses have nothing to do with whether the piping is straight or not. There will be acceleration losses (or gains) everytime there is a change in the fluid's velocity. Acceleration is most important in two phase flow (especially when flashing), less so in gas flows, and usually neglected in single phase liquid flow. (This, of course, is an oversimplification since even in liquid flow you consider entry and exit losses, which are acceleration losses.)

Hi, Jetul,
I tried to sent you the files that you requested me, but for the size of file was impossible.

Instead, I attach an PDF file about Two phase flow and its worksheet for aplication

I think that this information will be useful to you

Good luck

Suresh,

Caution should be taken when you are using only two parameters to determine flow pattern in two phase flow pipes:
Taitel and Dukler discussed various available coordinate systems, and argued that flow pattern transitions can not all be described by any one coordinate pair.

I need to know the general method or formula to calculate pressure drop in pipe lines in engineering industry.

my mail id is vinee43@yahoo.com, kindly send me the documents.

Vinee,

What can be more general than Fanning equation?
If you use Google for exploring the topic "pipe friction losses", you'll find thousands of on-target results.

Best regards,

Hi Profe,

I am also interested in two-phase problem,
could you send the file to me? thanks a lot.

Dear Profe,

i'm designing a shell & tube condenser, in wich the condensation is in the tube side. i am trying to calculate a two phase pressure drop but can't find a good info related to this problem. Would you please send me the information that you've sent to another user of this forum?

My e-mail address is: antonfedak@gmail.com

Thanks in advance!
