1. What Is Compression Ratio?

Compression Ratio is the ratio of the absolute stage discharge pressure to the absolute stage suction pressure. It represents the degree to which a fluid is compressed in a system.

2. How Does The Calculator Work?

The calculator uses the compression ratio formula:

Where:

• \( r \) — Compression Ratio
• \( V_s \) — Suction Volume (m³)
• \( V_2 \) — Discharge Volume (m³)

Explanation: The compression ratio is calculated by dividing the suction volume by the discharge volume, showing how much the volume decreases during compression.

3. Importance Of Compression Ratio Calculation

Details: Accurate compression ratio calculation is crucial for designing and optimizing compression systems, ensuring efficient operation, and preventing mechanical failures in compressors and related equipment.

4. Using The Calculator

Tips: Enter suction volume and discharge volume in cubic meters. Both values must be positive numbers greater than zero for accurate calculation.

5. Frequently Asked Questions (FAQ)

Q1: What is a typical compression ratio range?
A: Compression ratios vary by application but typically range from 2:1 to 20:1 depending on the compressor type and system requirements.

Q2: How does compression ratio affect efficiency?
A: Higher compression ratios generally improve efficiency but may increase mechanical stress and temperature rise in the system.

Q3: Can compression ratio be less than 1?
A: No, compression ratio should always be greater than 1 since discharge volume is smaller than suction volume due to compression.

Q4: What factors affect compression ratio?
A: System design, compressor type, operating conditions, and fluid properties all influence the compression ratio.

Q5: How is compression ratio related to pressure ratio?
A: For ideal gases, compression ratio equals pressure ratio when temperature remains constant (isothermal compression).
