Reciprocating Compressor Volumetric Efficiency Calculator

Calculate Volumetric Efficiency (Ev)



Formula

The formula to calculate the Volumetric Efficiency (Ev) is:

\[ E_v = \left( \frac{V_s}{V_d} \right) \times 100 \]

Where:

What is Volumetric Efficiency?

Volumetric Efficiency (Ev) is a ratio or percentage of the total volume of air delivered by a compressor compared to the total swept volume. It is an important parameter in evaluating the performance of a reciprocating compressor. Higher volumetric efficiency indicates better performance as it signifies that the compressor is delivering a larger volume of air relative to its size.

Example Calculation

Let's assume the following values:

Using the formula to calculate the Volumetric Efficiency:

\[ E_v = \left( \frac{2}{3} \right) \times 100 = 66.67 \% \]

The Volumetric Efficiency is 66.67%.
