Many thanks, Asymptotic and Pratyeka for your answers and information regarding the sensitive flame. It's always nice to be able to able to clear up a mystery. I'll be sure to show the answer to my colleague who noticed the phenomenon.

Sorry, I had the videos set to private on YouTube. I've just tried them in another browser and they should load now.

I moved the rig to another location in order to get a bit more peace. Even so, I decided that I won't be conducting any more tests, because people where I work have a habit of asking lots of questions and are generally suspicious, which means that I was only able to do a couple of tests with 1...

That's interesting. I'll try my best to get something done this week, but as I said, no longer being in that department means I'll have to wait until everyone else has gone home.

Hi, Pratyeka, The change in the pilot light starts instantly with activation of the air gun and also stops instantly with deactivation of the air gun. I've no idea of the size of the room. It's a fairly large hall. I'll try and get back with a rough idea of how much area it covers tomorrow. It's...

Yes, that's pretty close to it.

Hi sophiecentaur, As I mentioned to Asymptotic, I'll try and get some photos done soon to clear up any confusion.

Hi Asymptotic, Yes, I'll try and take a camera with me at some point and incorporate your suggestion with the cardboard box. I just have to make sure I do it after my colleagues and supervisor have gone home, as it's forbidden to take photos where I work. Not that I haven't done it before in...

Sorry, I meant tap the cylinder valve, not regulator. I can't find any pictures of these. The best way I can describe these cylinder valves is that they have curved levers for handles, which you pull up towards you to open the flow and push down away from you to shut off the flow. The actual...

Thanks for your suggestions, sophiecentaur. I'll give them a try when I get the chance, though it may take a while, due to me having been moved to a different working area. I can't manage different air guns (they're all of one type), though perhaps I could try with different feed pressures as...

This has been bugging me for a few months now, and I'm hoping that someone can provide me with an answer. A while ago, my colleague was soldering with an oxy-acetylene torch and paused for a few moments in between jobs, leaving only the pilot light on top of the unit burning. Sitting about 4-5...

Hi kuruman, I conducted several, but got sick of pages and pages of information about half-life etc. Luckily I've just tried again and lo and behold I found a page which told me the following: 'The energies of both the beta decay of cesium-137 and the subsequent gamma decay of the excited barium...

Homework Statement The half-value layer (thickness) of gamma rays in lead is dependent on the energy of the gamma photons before they enter the lead. Find the graph which shows the relationship between the energy of the gamma photons (pasted below) and the half-value layer and read their...

It's okay. I worked out where I was going wrong.

Homework Statement I'm working through some exercises in which I'm supposed to convert various units of speed from SI units to other units Example: 0.4m/s into km/h Homework Equations The Attempt at a Solution Having checked, I know my answer to be (to 3 significant figures) correct. My...
