To enhance compressor flexibility it is desirable to design into the compressor the capability of operating at other than the original design conditions. If it…

Using a known piston displacement and efficiency, the gas throughput can be calculated from:

The flow rate is not directly equal to the piston displacement. Volumetric efficiency is the ratio of actual volumetric flow at inlet temperature and pressure…

The actual volume of the cylinder that is swept by the piston per minute is piston displacement. It can be calculated from: Single acting cylinder…

Typically, in specifying a unit, the suction and discharge pressures, capacity (MMscfd), inlet temperature, and gas properties are given. The actual sizing of the cylinders…
