Question 595Steam Plants - Assistant Engineer70% to pass
In which type of turbine does a pressure drop exist through the fixed blades and the moving blades?
AI Explanation
The correct answer is C) Reaction.
In a reaction turbine, there is a pressure drop through both the fixed blades (stator) and the moving blades (rotor). This pressure drop across the blades is a key characteristic of reaction turbines, which rely on the change in pressure and velocity of the working fluid to generate power.
The other options are not correct because:
A) Curtis and D) Impulse turbines do not have a pressure drop through the moving blades, only through the fixed blades.
B) Rateau turbines are a type of impulse turbine, which also do not have a pressure drop through the moving blades.
