Why does air heat as it's compressed?

Damn you RustyJC

Dammit JC Creekmore, that equation seems to work. when gamma is = to zero it decomposes to regular gas laws.



I thought we were going to argue it abstractly. Now you come up with an equation and kill the thread dead in its traks.



If that is going to be your tact from now on then I wont PM you anymore, you already stole 7$ from me

Have any of you ever seen or used a small tool called a fire piston? They are used for starting fires or lighting your smokes. They are pretty neat I think. Try a Google search and you can see what they look like.

tell us more about the fire piston

The adiabatic processes! I knew it would be something simple like that.

Fire Piston

I was watching a BBC show called "Engines that changed the world" with Robbie Coltrane as the host (great show). It was the episode on diesels and he was going over the origin of the diesel. The way he explained it, Rudolph Diesel was sitting in class one day watching a demonstration of what they called the "Malayan Fire Piston", Diesel wrote down in his notes, "Study, whether it is possible, to achieve the isotherm in practice". With that he says, "the Diesel engine was born".

Wish I knew what an Isotherm is .



Here's a good link: fire piston

OK, so I cheated a little bit. In addition to engines, our company manufactures turbochargers and compressors, so I have to deal with adiabatic, polytropic and isentropic compression calculations pretty often. And I still have that $7. 00 in my wallet!
