If pressure and temperature drop after the turbine, it would not necessarily be the result of the interaction with the turbine. How would airflow routed through the turbine reduce temperature or pressure? Those would more likely be the result of expansion. If volume remains constant, pressure would actually increase after passing the turbine. I don't see how heat energy is transferred to turbine energy at all. But, since MarkB studied thermodynamics and the rest of us didn't, maybe he can explain. It is the kinetic energy (not heat energy) which is comprised primarily of velocity and density(mass) which is transferred to the turbine. The change in velocity is the measure of energy imparted. Those are my uneducated thoughts, at least. I think most people got pretty close to getting it right.

Despite having to disassemble the majority of my John Deere 2010's diesel engine, I was still hopeful I could leave the engine-complete with crankshaft and camshaft-in the tractor. This would make the whole engine rebuild job much easier-and much less expensive! I soon found however, that the #4 conrod bearing had disintegrated, taking with it chunks of the crankshaft journal. As a resul
