_____________ is the ratio of the absolute pressure at the discharge from a compressor divided by the absolute pressure at the suction
Direct Answer
Option B: Compression Ratio
Compression ratio represents the thermodynamic efficiency and mechanical stress applied to a compressor. It is calculated by dividing the absolute discharge pressure by the absolute suction pressure. Maintaining this ratio within design limits is critical for preventing overheating and mechanical failure in shipboard LNG fuel gas compressors.
