Watch this one go down in flames:
< In impulse steam turbines (such as those made by deLavel), the size
of the inlet
< and outlet are vastly different cross-section, and pressures.
The de Lavel GAS turbine isn't for a condensable vapor but for
obtaining rotational shaft work from the kinetic energy from an ALREADY
FULLY EXPANDED, NON CONDENSABLE GAS in a gas turbine engine. The
pressure is the same BEFORE entering the stator blading as AFTER
leaving the rotor -- atmospheric.
The exact same energy conversion situation as wind turbines.
< In gas turbines, the *turbine* is 80% efficient, but the inlet
pressure is much
< higher than the outlet pressure
You are really showing your ignorance of gas turbo now. That is the
REACTION, or more generally, the part reaction-part impulse turbine
typically used in multi stage aviation turbines, NOT the 100% impulse
turbine of de Lavel.
And those turbines have efficiencies of EIGHTY NINE PERCENT (89%), NOT
80%.
It's now obvious you are so clueless about gas turbo you have never
even seen a vector diagram like those used to design flow machinery --
not for an axial compressor and not for an axial flow turbine.
Come on, search "vector diagram" + "gas turbine" and "Westinghouse"
before you post again.
