I beleive CRANE valves company do have one

Hello Kmuhsen, thanks a lot for your quick answer! I'll try to found more about Crane technical tips on its HP. I know only about Crane famous book about hydraulics accesories and related topics.
There are a lot of demos softwares avaiable, but I need asap some complete (no demo) for free in order to make a simply piping simulation.

By the way, where are you from? I'm a brazilian mech. engineer. See more on my HP (http://www.geocities/Eureka/Gold/7933)

Best regards - keep in contact!

Unfortunately the Crane software is not free and the book, Technical Paper 410 (TP-410) is not free, but if you whine at the local Crane rep you can probably get the book which comes in both US and metric versions. I've used them both, and they are the definitive methods. If you can live with calculator programs there are some good ones available for the HP48.
