How do you calculate swept volume of a compressor?
Swept Volume = pi*(bore/2)^2*stroke. try this. take the bore and divide it by 2. by doing this, you have the radius of the cylinder.
What is swept volume in reciprocating compressor?
Swept volume is the displacement of one cylinder. It is the volume between top dead center (TDC) and bottom dead center (BDC). As the piston travels from top to bottom, it “sweeps” its total volume. This measurement can be listed in cubic inches or cubic centimeters.
How do you calculate reciprocating compressor capacity?
In general the capacity of the compressor is given by the formula:
- Capacity = Π * D2 * L * N * n/4.
- R = Absolute suction pressure of the refrigerant/ absolute discharge pressure of the refrigerant.
- V = Actual volume of gas sucked by the compressor/ Theoretical volume of the compressor.
How do you calculate the volume of a compressor?
Eg: CFM (Cubic Feet per Minute) – Cubic Feet is a unit of volume and minutes is a unit of time. 1 cubic foot is = 28.317 Liters. Therefore 1 CFM = 28.31 (LPM) Liters Per Minute. Similarly Liters per Second (L/sec) or Cubic Meter per hour are units of flow of air.
What is the capacity of reciprocating compressor?
The “typical” reciprocating compressor is used for discharge pressures up to 12,000 psi (828 bar). Special compressors (called hypercompressors) are used in low-density polyethylene production and discharge at pressures up to 50,000 psi (3500 bar).
What is compressor capacity?
Compressor capacity can be defined as the amount of air the unit is able to pump out. While a small and large compressor can have the same pressure capabilities, the larger model has a greater capacity to produce more compressed air. Capacity is expressed in terms of cubic feet per minute (CFM).
What is compressor pressure ratio?
We measure the increase by the compressor pressure ratio (CPR), which is the ratio of the air total pressure pt exiting the compressor to the air pressure entering the compressor. This number is always greater than 1.0. To produce the increase in pressure, the compressor must perform work on the flow.
What are 4 types of compressor capacity control?
The main capacity control methods for reciprocating compressors are variable-speed drives, suction valve unloaders, step-less methods, clearance pockets and bypass recycling.
Which compressor has highest capacity?

How do I calculate air compressor cfm?
How Do You Calculate CFM for an Air Compressor?
- Next, convert to standard pressure (ATM).
- Tank Pump-up Time = 1 min 8.4 seconds (1.14 minutes)
- The three primary factors are:
- CFM = Tank Volume in Cubic Feet x Standard Pressure (ATM) During a Cycle x Cranks per Minute.
