Wondrous Q for people who are better at thermo than I am:

Here's something I've always wondered about these try-cocks in stead of a gauge glass. When you open one of 'em, I've always thought the following happens:
  • If there's steam behind it, it goes wisshhhhhh and a cloud of steam comes out.
  • If theres water behind it, that water must be at saturation temperature of the boiler pressure, and instantly flashes to steam when it comes into contact with the atmosphere. So it still goes wisshhhh and steam comes out.

So then, how are these things useful when trying to establish whether I should run an injector or not?

Started texturing lately, so this isn't completely dead yet. The objective is to have the entire model in one 4096x4096 ubershader, with the normals uncompressed at 2048x2048. That'll give me approximately a memory footpring of 65 Mb, give or take a couple of extra textures for autonumbers, decals, and bits I forgot to UV...

You should submit this stuff to some Steam Punk art competition, for added return on investment. There are people who do just that, without ever caring about physics and realism.

I see your question about the cocks just now. I would say that those who operated them knew the difference in wissshhh. Personally, I would have assumed that the steam that might form from the water would be very wet steam that condenses quickly while the steam that was steam inside the boiler would be dryer and look different as a cloud. But that is totally unscientific thinking. But then again, even if there is the same pressure everywhere in the boiler, the water that is still liquid must be different from the water that is already steam and the difference can only be the temperature. So the steam that had been water before it came out of the cock must be a little cooler than the steam that had been steam inside the boiler. This could then lead to a visible difference in the clouds formed in the two cases.
