How to Evaluate Volumetric Efficiency of Reciprocating Compressor?

Volumetric Efficiency of Reciprocating Compressor evaluator uses Volumetric Efficiency = Actual Volume/Piston Swept Volume to evaluate the Volumetric Efficiency, The Volumetric Efficiency of Reciprocating Compressor represents the efficiency of a compressor cylinder to compress gas. It may be defined as the ratio of the volume of gas actually delivered to the piston displacement, corrected to suction temperature and pressure. The principal reasons that the cylinder will not deliver the piston displacement capacity are wire-drawing, a throttling effect on the valves; heating of the gas during admission to the cylinder; leakage past valves and piston rings; and re-expansion of the gas trapped in the clearance-volume space from the previous stroke. Re-expansion has by far the greatest effect on volumetric efficiency. Volumetric Efficiency is denoted by η_v symbol.
