I should correct my self. It should be Vortex Cone not tube, us vortex tube have different function. Sorry for that.

It look like there a lot of variable that determine the total efficiency. I read somewhere that if you compare the energy generated in hydro power plant with particular elevation to power plant with the same elevation that contain vortex tube the last one will generate more power . The...

The pressure is not random, the molecules in the fluid have random movement besides the overall push of feed pump. Basically each molecule is independent entity. Each molecule “attacking” the turbine under different angle even if they have general direction of the movement. That mean not all...

Interesting. I am electrical , specially in RF and uW, so of this might be of base. I never know that the boiler feed pump could have such impact on the overall efficiency. My assumption was that the base ranking cycle (temperature pressure differential) is the limit. I look around and...

I wonder why water turbine (like in hydroelectric power plant) has, in most design, more then 90% efficiency when steam turbine around 30%. In both cases we converting the pressure to work, so why such a difference in efficiency?

Lojzek How about water gun or pneumatic gun, can it be consider a heat engine? In both cases you have pressure reservoir (pressure can be consider as a heat reservoir). In such case we have to consider the idea of external combustion. There might be another consideration: In both cases ...
