This formula uses 5 Variables
Variables Used
Volumetric Efficiency of Compressor - Volumetric Efficiency of Compressor is the ratio of the actual volume of refrigerant passing through the compressor per cycle (Vs) to the stroke of the volume of the compressor (Vp).
Clearance Factor - Clearance factor is the ratio of clearance volume to the piston displacement volume.
Discharge Pressure of Refrigerant - (Measured in Pascal) - The discharge pressure of refrigerant is the pressure of the refrigerant after the compression stage or it is the pressure of the refrigerant at the discharge.
Suction Pressure - (Measured in Pascal) - The Suction Pressure is the pressure of the refrigerant before the compression. It is also called the suction pressure of the refrigerant.
Polytropic index of Compression - Polytropic index of compression is a parameter that defines the relationship between pressure and volume during a thermodynamic process. It indicates how heat is transferred during compression.
STEP 1: Convert Input(s) to Base Unit
Clearance Factor: 1.24 --> No Conversion Required
Discharge Pressure of Refrigerant: 8 Bar --> 800000 Pascal (Check conversion ​here)
Suction Pressure: 1.013 Bar --> 101300 Pascal (Check conversion ​here)
Polytropic index of Compression: 1.3 --> No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
ηv = 1+C-(C*(P2/P1)^(1/nc)) --> 1+1.24-(1.24*(800000/101300)^(1/1.3))
Evaluating ... ...

How does clearance volume affect volumetric efficiency?

An increase in clearance volume causes a decrease in volumetric efficiency. An increase in compression ratio also decreases the volumetric efficiency. Piston ring leakage allows gas from the compression chamber to escape the piston and enter the other end of the cylinder. This reduces the volumetric efficiency.
