    Dispersion Model and jet flame length

    You could also think about how long the jet flame would stay at the initial length for - as the system depressurises, then the flame will get smaller, and it may not impinge on your pipework long enough to give you a problem. If you could stick an ESDV somewhere, perhaps with remote actuation...

    Depressurisation of Cross-Country Line

    Thanks for the kick in the right direction David - getting there now I think!

    Depressurisation of Cross-Country Line

    Hi, I'm working on a problem, which I think should be relatively simple but I'm tying myself into knots over, so I thought posting here might help re-focus my tired brain. It can be embarrassing to keep going back to your boss... The problem involves a large pipeline transporting unstabilised...

    Antoine constants for Chlorine Dioxide - P in mmHg

    That also seems to work siretb, but when I did it the way montemayor suggested, I got values for the constants that were far more in line (i.e. same order of magnitude etc.)with the existing values for other compounds in the database I was adding to. Curious. Amazing how quickly you forget the...

    Antoine constants for Chlorine Dioxide - P in mmHg

    Thanks for the quick responses. I should have been clearer, I do actually know how to convert from bar to mmHg, but not how to convert the Antoine constants! Montemayor's idea is a good one, and one I should have thought of. Thanks.

    Antoine constants for Chlorine Dioxide - P in mmHg

    I've been searching for a while now (it probably feels like longer than it really is) for antoine constants for chlorine dioxide, to give vapour pressure in mmHg. I've found constants to give vapour pressure in bar, but not mmHg (my consequence analysis software requires them in this form). Or...

    Converting an H2S analysis result in ppm (w/w) to ppm (v/v

    Hi, I've got a sulphur survey in which results are presented in ppm (w/w) (i.e. mg/kg). I need, in order to do some classifcation of our plant based on H2S concentrations, the results in ppm (v/v). I thought I knew how to convert this using molecular weights and assuming ideal gases etc. but...
