Question 1 of 27070

🔍 Key Concepts

• the meaning of cross compound vs tandem compound turbine arrangements • how steam flow path (series vs parallel) relates to the naming of turbine types • what it means for two turbines to drive a common reduction gear through separate shafts

💭 Think About

• Identify which choice describes turbines arranged on a common axis versus on separate axes • Ask yourself: in the question, is the key feature the steam flow path, the shaft arrangement, or both? • Match the described setup (HP then LP, both to one reduction gear) to the standard textbook definitions of each option

✅ Before You Answer

• Verify which term applies when two separate turbine casings drive one reduction gear via separate pinions/shafts • Check whether cross compound usually involves more than one shaft line to the propeller vs a single shaft line with a common reduction gear • Confirm how tandem arrangements normally position HP and LP turbines relative to each other (same shaft or different shafts?)
