I have a second CO2 extinguisher which has a 14 cm long metal tube between the input to the horn and the cylinder output. This is an unmodified commercial extinguisher. I don't know where the pressure reduction hole is on this one so the tube may not in fact be tolerating tank pressure but there...
Yes, I know all this. But what is the purpose of the 1 mm dia hole just before the input to the horn? I keep asking this question and all I get is a lecture about something else, something obvious and which I already knew. Please, somebody tell me the purpose of the 1 mm dia hole. Why so small...
Nidum, your link doesn't explain the purpose of item 22, the nozzle. russ waters, of course it's purpose is to extinguish fires. That's what I want it for. But have you ever tried holding a 5 Kg CO2 extinguisher close enough to a fire to put it out? My purpose in extending the tube was to allow...
Thanks everyone. In that case boneh3ad would you agree that it wouldn't matter where in the pipe leading from the tank to the horn at the output end the restriction was placed? The reason I'm asking about this restriction is that I want make a 1.5 m long plastic extension on the end of the...
We talk about the properties which energy has and about its many forms but we never say what it is. I think that spacetime must vibrate in certain ways so as to create energy. What energy is, is then contained in a description of that vibration. Any ideas, anyone?
1. An oscilloscope generates a moving spot which moves fast enough to be able to resolve the wave of the electric component after amplification and display an analogy of it on a phosphor. We can then calculate the distance between peaks knowing the frequency and the speed of travel in space.

Hi. Can I say it seems to me that none of the standard or non standard explanations are very true. I think they are the best theories we can come up with in the hope that they will somehow spawn a better predictive capability but in another sense they are all just attempts to cover the fact that...
What do members think of the idea that the philosophy which began quantum theory in the first place was inadequate to explain and describe reality in a sufficiently deep way, so that we now have a theory which in many ways fails to describe the reality which we experience in the world?
