WebbIn a Parson’s reaction turbine the rotor of 1m diameter runs at 3000 rpm. Determine the isentropic enthalpy drop in the stage considering stage efficiency of 0.80 , ρ = 0.7, blade outlet angle = 20°. Step-by-Step. Verified Answer. This Problem has been solved. WebbThe first turbine of which there is any record was made by Hero of Alexandria, 2,000 years ago, and it is probably obvious to most persons that some power can be obtained from a jet of steam either by the reaction of the jet itself, like a rocket or by its impact on some kind of paddle wheel. About the year 1837 several reaction steam wheels

Steam enters through nozzles at the top (yellow) then passes between a series of moving (blue) and stationary (red) blades before exiting at the bottom. It hits each blade and bounces off—just like in a simple impulse turbine.
