Hi How can I estimate the maximum flow in NPS 4" piping if we drain LPG from a pressure vessel to atmosphere using that piping? Actually, I need to calculate the maximun thrust at the end of the piping. I understand that if I use Bernoully, introducing friction losses, I can estimate the...

Thank you for your advise. I will try it

SultanSaladin I have reviewed that Web page and I found that implementations of the API are currently available for Solaris SPARC, Solaris x86, and Linux x86. Actually I know that Java manage the serial port with its own API. But, does the Java communications API will recognise a...

Thank you for your advice. How can I remove the post from this forum?

xwb Thanks for your answer When you say "will probably have write it in C", means that it is not possible to do it with Java?

Hi We have a small visual basic application to collect data from controlers. PC has Windows XP Professional and has a multiport RS232 card. We have to replace the old application and we will develop the new one using Java. We understand that Java does not use Win32 Serial API. Has one of you...

I will appreciate your help on the following: Which are the difference between ANSI B73.1 and ANSI B73.1M?

I am looking for information about conditional diagramming method for activity sequencing like: Grapgical Evaluation and Review Technique (GERT) or System Dynamics I will appreciate any help you can give.

Tamrak Have you try to “copy” each cell of the project table and “paste special” with link in excel?

Saldanha: we received lpg by ship and unloaded by truck. We suppose that the N2 comes from the ships and trucs (line of return from the loading facilities). We don't use LPG, only store it (300 m3 of capacity)

We have taken LPG's sample (vapor) from the top of the tank and we have found a significant value of nitrogen. 1 The presence of nitrogen can affect the conditions of storage (pressure/temperature)? 2 Do we have to purge it totally? 3 If yes, which is the best method? 4 Which is the best...

A volume of liquid trapped in an enclosed piping system has the potential to expand with a corresponding rise in ambient temperature, How can I relieve that over pressure in LPG and gasoline pipings? Is a relieve valve the better solution?
