Volumetric Efficiency (Ev):

Volumetric efficiency is a crucial parameter in evaluating the performance of reciprocating compressors. It represents the ratio of the actual volume of gas drawn into the cylinder to the displacement volume of the compressor. Our Reciprocating Compressor Volumetric Efficiency Calculator simplifies this calculation, enabling you to determine the volumetric efficiency effortlessly.

Formula

The formula to calculate volumetric efficiency is: Volumetric Efficiency (Ev) = (Swept Volume (Vs) / Displacement Volume (Vd)) * 100

How to Use

1. Enter the swept volume (Vs) in the provided field.
2. Enter the displacement volume (Vd) in the provided field.
3. Click the “Calculate” button to see the volumetric efficiency.
4. The result will be displayed in the output box below the calculator.

Example

Imagine a reciprocating compressor with a swept volume of 500 cubic centimeters (cc) and a displacement volume of 600 cubic centimeters (cc). By inputting these values into the calculator, you’ll find that the volumetric efficiency is approximately 83.33%.
