Authoritative reference for "pipe/flow sizing nomogram" 5

[ginsoakedboy]

I often need to size piping/tubing to allow highest flow-rate for heat transfer purposes, and I am not very familiar with Piping or Pipelines-related industry standards.

So, I have to turn to web-based sources for information. Many of the supplier websites recommend the use of the "pipe/flow sizing nomogram". I have attached an example.

Can anyone point me to the original reference publication(s) or standard(s) that may be referenced in technical reports rather than these websites that be unreliable?

Thank you in advance.

moltenmetal,
I don't think that I've ever forgotten that im my life. I also know that I make better economic decisions if I have better technical data. If a nomograph says I'm going to exceed my design velocity with 6-inch, I can either put 8-inch into the economics or I can use an actual equation and see if the assumptions in the nomograph were too conservative and running the isothermal gas flow equation says that 6-inch is fine. Can make a big difference in the project.

Thank you all for sharing a wealth of insight and experience. This thread has added to my knowledge immensely and made me wary of using the widely available nomographs. The inherent complexity involved in fluid flow phenomena is underscored in multiple posts.

Which one of Handbook of Hydraulics by Brater and King, Cranes Flow Manual or Crane TP 410 be appropriate to gain better understanding without spending hours and hours studying? (Note that my designs will be checked by multiple parties before approval for manufacturing.)

I've never read Brater and King. I've used Crane TP 410 for many, many years. It is concise with many worked examples and it's not very expensive. It's methodology is accepted around the world as technically rigorous.

Good luck,
Latexman

I've never read Crane, but I have used my 6th edition Brater and King for over 26 years (first edition published in 1918) and it is also accepted around the world (by most civil engineers). There are no worked examples, however most equations have a full derivation.

I believe Crane is more for industrial process piping and Brater and King more for irrigation and dams...
