Crane Technical Paper No. 410 Flow of Fluids Through Valves, Fittings, and Pipe, also known as TP410, is remarkably important to the field of hydraulic calculations. With it's standard equations and research-derived methods for quickly and practically calculating pressure loss due to fittings like valves and pipe elbows, it is on many an engineer's desk. I have heard it described as "the closest thing to a standard on hydraulics the [chemical] industry has." I have the imperial and metric versions of it.
So, I thought I would mention that they are publishing a big new revision of TP410. The US units version in November, and the metric version soon after.
For the 2009 edition, additional valves and their resistance coefficients were added based on tests performed within the Crane Engineering Laboratories. Industry research was gathered on the latest calculation methods for hydraulic resistance and in resistance values for wyes and tees. Chapters on pumps, control valves, and flow meters were included and over thirty-five new sources have been added to the book.
TP-410 is published by Crane Co., one of the world's leading suppliers of valve products and services.
Also, they are tying the book in closely to web-based Crane TP 410 tools, some of which are already up and free. Like pipeline pressure and head losses due to friction, and converting between Crane "K" factors and valve Cv factors.
Will these new features be worth buying the book for those who do not have it? I don't know. I don't have any inside information. I just thought this would be noteworthy to a few of you, as it's not very publicized.
Lastly, as a bonus, here's some interesting reading on TP410:
