🔍 Key Concepts

• Overall compressor pressure ratio is the product of the pressure rise across each stage • Axial compressors typically have a modest pressure ratio per stage (well under 2:1) • Number of stages and typical per‑stage ratios can be used to estimate a realistic design pressure ratio range

💭 Think About

• From the illustration, count how many compressor stages are present and think about whether each stage can realistically double the pressure • Compare the listed answer choices with a typical total pressure ratio for a 16‑stage axial compressor on a marine gas turbine • Ask yourself which options are unrealistically high or low if each stage only adds a small fraction (for example, around 1.1–1.3:1) to the pressure

✅ Before You Answer

• Confirm the total number of compressor stages shown in the figure (note the labels: Stage 1…Stage 16) • Estimate a reasonable pressure ratio per stage for an axial compressor and multiply by the number of stages to see which option is most plausible • Eliminate any answers that would require an unrealistically large pressure rise per stage for this type of compressor
