Q

In which type of turbine does a pressure drop exist through the fixed blades and the moving blades?

🔍 Key Concepts

• Difference between impulse and reaction turbines • Where the pressure drop occurs in turbine stages (nozzles/fixed blades vs moving blades) • How compound impulse designs like Rateau and Curtis stages handle pressure and velocity changes

💭 Think About

• Ask yourself: In which turbine type does the steam lose pressure ONLY in the nozzles/fixed blades, and what does that tell you about the moving blades? • Which turbine type is specifically defined by having pressure drop across BOTH the fixed and rotating elements? • How are Rateau and Curtis stages constructed—are they pure impulse, pure reaction, or special ways of arranging impulse stages?

✅ Before You Answer

• Be clear on the definition of an impulse turbine: where is the pressure drop, and what happens in the moving blades? • Be clear on the definition of a reaction turbine: where is the pressure drop, and what happens in the moving blades? • Confirm whether Rateau and Curtis are forms of impulse staging or a different fundamental turbine type.
