🔍 Key Concepts

• purpose of a constant speed governor in turbine operation • difference between constant speed and variable speed applications • which turbine-driven systems must maintain a steady frequency or RPM to function correctly

💭 Think About

• Ask which of the listed turbine applications absolutely requires its speed to stay nearly constant during normal operation. • Consider which system’s output would be seriously affected (e.g., frequency, synchronicity) if the turbine speed changed noticeably. • Think about how shipboard electrical power is produced and what must stay constant for that power to be usable across the vessel.

✅ Before You Answer

• Identify which option is directly tied to producing electrical power at a fixed frequency. • Eliminate any options where turbine speed normally varies with load or operating condition. • Confirm which system’s safe/efficient operation depends on holding RPM constant rather than allowing wide speed variation.
