BIGF Exit Exam • Set 3 Question 12 of 30

Compression Ratio is the ratio of the absolute _____________ the discharge from a compressor divided by the absolute pressure at the suction

✓

Direct Answer

Option C: pressure

Compression ratio is defined as the quotient of absolute discharge pressure over absolute suction pressure. This dimensionless value is a primary indicator of compressor performance and mechanical load. Monitoring this ratio is essential for safe operation of fuel gas compressors within the IGF Code's fuel supply system requirements.

All Options

A
mass
B
temperature
C
pressure (Correct Answer)
D
volume

Detailed Explanation & Context

Compression ratio is defined as the quotient of absolute discharge pressure over absolute suction pressure. This dimensionless value is a primary indicator of compressor performance and mechanical load.
