Concerning the classification of steam turbines, a cross compound designed unit __________.

🔍 Key Concepts

• Cross-compound vs tandem-compound steam turbine arrangements • Difference between shaft layout (how many shafts and how they’re connected) and stage design (impulse, reaction, Curtis) • What a Curtis stage and reaction staging actually describe

💭 Think About

• First decide: does “cross compound” describe (a) how many shafts/turbines and how they are connected, or (b) the detailed type of blading/staging inside the turbine? • Look at each choice and ask: is this talking about the physical arrangement of multiple turbine units on shafts, or is it talking about internal blade/stage design? • Think about which term — cross-compound, tandem-compound, or combination impulse-reaction — would normally be used for each description given in the choices.

✅ Before You Answer

• Identify which option clearly describes an arrangement of separate high- and low-pressure turbine units working together, versus those that only describe blade/stage types. • Verify what a Curtis stage is (impulse stage with velocity compounding) and whether that alone defines a cross-compound turbine. • Check which options mention features (dummy piston, mixed staging) that are common to many reaction/combination turbines but do not specifically define a cross-compound arrangement.
