Where:

- Bore Area = (π * (Bore Diameter / 2)^2) in square inches
- Stroke is in inches
- Cycle Rate is in cycles per minute
- Pressure is in pounds per square inch (PSI)
- 1728 is used to convert cubic inches to cubic feet (12^3)

**How much air does a pneumatic cylinder use?** The air consumption of a pneumatic cylinder depends on its size (bore diameter and stroke), operating pressure, and cycle rate. It can vary widely from a few CFM (cubic feet per minute) for small cylinders to several CFM or more for larger, high-frequency applications.

**How do you convert PSI to SCFM?** You cannot directly convert PSI (pressure) to SCFM (air flow) because they are different measurements. SCFM is a measure of air flow, while PSI is a measure of pressure. To determine SCFM, you need to measure or calculate the actual air flow rate under specific conditions.

**What is the relationship between pressure and CFM?** The relationship between pressure and CFM is typically linear, meaning that as pressure increases, CFM decreases, and vice versa. However, this relationship depends on the characteristics of the pneumatic system and devices.
