🔍 Key Concepts

• Common engine-room and machinery acronyms used on license exams • Functions and measurements associated with compressors in marine engineering • Difference between a temperature-measuring device and a pressure-indicating term

💭 Think About

• Ask yourself: when engineers talk about conditions at the discharge side of a compressor, which physical quantities are they most concerned about? • Which option names a device that directly measures temperature, and which option describes a quantity that would typically be monitored or controlled? • Eliminate any options that are not normally standard engineering terminology you’ve seen in marine engineering texts or drawings.

✅ Before You Answer

• Identify which choices relate specifically to compressor systems • Determine which terms refer to measured variables (like pressure or temperature) versus mechanical locations or points • Check your engineering references or notes for standard abbreviations used with compressor discharge readings
