Dear all,
As some of you know, i'm currently doing a small thesis on Greek Fire (Yes I know it is Byzantine warfare). My question: How much pressure could bronze tubes and cauldrons take? Ie, could liquids inside be pressurized and to what extent before the entire thing pops? Just to be safe i've put it here, with engineering.
Many thanks,
Regards,
Hans

I would suppose that it could vary widely, based upon the thickness and quality of the materials, as well as the craftsmanship.

It would be also of interest whether the stream of liquid was ejected continuously or with interruptions. This question has been hardly addressed in the scientific debate, at least in the half dozen articles I read.

Do we know how thin bronze pipes were sealed? That might affect things. Thick, heavy pipes could be cast. I'm remembering the scenes in Lest Darkness Fall where Martinus tries to make tubing for a still, although that was researched seventy years ago.

I have not checked this forum frequently since 2013, but I hope that these old posts have some value. I now have
a blog on books, swords, and the curious things humans do with them.

I have discarded the pressure-hypotheses because it is simply too dangerous to have on a wooden vessel.
I'm going to do a few rough calculations on the Byrne-Haldon model (With a double-action force-pump).
Thus, i need the dimensions of the force-pumps in the Roman timeframe. A few have been found. Does anyone know where I can get hold of some dimensions?
