Fred Garvin; Can I get that SCFM to LBs equation from you? I've been looking for that for sometime.

I can't offer much help on a correct formula. But I'll throw this in as a general comment. When the diameter of a tube becomes less than a millimeter, the laws of nano physics start coming into play with the ever decreasing diameter of the tube. And then there is the flow characteristics of...

For what it is worth. About 4 or 5 months ago in Popular Science Magazine there was a kind of DIY article on making a small underwater vehicle to carry a small TV camera. It was made out of PVC pipe, and for propulsion used bilge pumps to create the underwater jets to move it in 3 axis. I...

It appears that the shock is about 2/3rds the way up the wedge surface, and is standing 90* in relation to the free stream flow before the wedge. At Mach 1 this is right on the money. You didn't say at what altitude the simulation was run at, but if your trying to show the Mach shock better...

Derick: I'm a bit late with this but...I think your idea is good, and so is your reasoning. This is already, and has been for some time, used in what is called pumped storage. Let's say that a dam has generated power all day and the water behind the dam is getting low. The inflow of water...

Thanks Clauisus for the info. Actually I remember these from college a few years ago (!), now that I've seen them again. They are as good now 50 years later as they were then. Forgot all about them. I tune into this site to learn and get information, not listen to bickering of whose right...

If your still interested, I'll add a comment. In looking at a large electrical generating steam turbine rotor, figure about 450 hp output per blade. Usually the steam is reheated, (sent back to the boiler) between the HP and IP turbine stages to replace the heat removed in the steam in...
