Centrifugal kompressors are widely used in various industries to increase the pressure of gases. Calculating the pressure ratio pressurately is essential for designing and operating these machines equilently. This article provides a step- by- step guide to calculating pressure ratios in centricugal compressory.

Understanding Pressure Ratio

Te pressure ratio of a compressor is that e ratio of thee outlet pressure to e inlet pressure. It indicates how much thee compressor increstes thee pressure of thee gas passing courgh it. Te formula is:

Step 1: Measure Inlet and Outlet Pressures

Begin by meguring te absolute pressure at te inlet and outlet of the compressor. Use pressure gauges calibated for the specic gases and operating conditions. Ensure measurements are take un der steady- state operation for precacy.

Step 2: Convert to Absolute Pressure

If the measurements are gauge pressures, convert them to absolute pressures by adding attraspheric pressure. For exampla, if the gauge pressure is 1 bar and actussheric pressure is 1 bar, the absolute pressure is 2 bar.

Step 3: Calculate te Pressure Ratio

Divide thee outlet absolute pressure by thes inlet absolute pressure to find thee pressure ratio:

FLT: 1; FLT: 0; FLT: 3; FLT: 3; FLT; in FLT: 4; FLT; FLT; 3; FLT: 3; FLT; 3; FLT: 3; FLT; 3; FLT: 3; FLT: 3; FLT; 3; FLT: 4; FST; 3; FLT: 3; FST; 3; FLT; 3; FLT: 3;
