Which of the following designs is an essential feature of the Rateau type turbine?

Question 1 of 27070

Which of the following designs is an essential feature of the Rateau type turbine?

🔍 Key Concepts

• Impulse turbine vs. reaction turbine basic design features • Difference between velocity compounding (Curtis) and pressure compounding (Rateau) • How steam pressure drop is distributed across nozzles and stages in different turbine types

💭 Think About

• Ask yourself: In a Rateau turbine, is the big pressure drop taken mostly in one place, or is it divided among several stages? • Which design feature specifically distinguishes a Rateau turbine from a general impulse turbine, something you would NOT automatically have in every impulse design? • Look at each choice and decide: Is this feature unique to a Rateau turbine, or is it common to many impulse designs or to a different named type (like Curtis)?

✅ Before You Answer

• For each choice, decide whether it describes pressure-compounded or velocity-compounded construction. • Identify which option could apply to almost ANY impulse turbine (and therefore is NOT uniquely "Rateau type"). • Verify which option clearly describes multiple impulse stages used to split the total pressure drop, and which option instead focuses on a single large drop or on velocity compounding.

Question 1 of 27070

Which of the following designs is an essential feature of the Rateau type turbine?

A large pressure and temperature drop occurring in the first stage.

The use of alternate rows of fixed and moving blades.

The use of a velocity-compounded impulse stage installed at the high pressure end of the turbine.

Two or more simple impulse stages aligned in tandem in one casing.
