This cylinder air consumption calculator helps engineers, technicians, and industrial professionals determine the air requirements for compressed air systems. By inputting key parameters, you can calculate the air consumption rate and optimize your compressed air system performance.
How to Use This Calculator
Using the cylinder air consumption calculator is straightforward. Follow these steps:
- Enter the cylinder diameter in millimeters
- Input the stroke length in millimeters
- Specify the number of strokes per minute
- Click the "Calculate" button
The calculator will display the air consumption rate in cubic meters per hour and provide additional information about the calculation.
Formula Explained
The cylinder air consumption is calculated using the following formula:
Air Consumption Formula
Air Consumption (m³/h) = (π × (Diameter/2)² × Stroke Length × RPM) / 60 × 1000
Where:
- Diameter is the cylinder bore diameter in millimeters
- Stroke Length is the piston travel distance in millimeters
- RPM is the number of strokes per minute
The formula accounts for the volume displaced by the piston during each stroke and converts the result to cubic meters per hour.
Worked Example
Let's calculate the air consumption for a cylinder with:
- Diameter: 50 mm
- Stroke Length: 100 mm
- RPM: 60 strokes per minute
Using the formula:
Calculation Steps
1. Calculate the cylinder area: (π × (50/2)²) = 1963.5 mm²
2. Multiply by stroke length: 1963.5 × 100 = 196,350 mm³
3. Multiply by RPM: 196,350 × 60 = 11,781,000 mm³/min
4. Convert to m³/h: 11,781,000 / 60 × 1000 = 1.9635 m³/h
The calculated air consumption is approximately 1.96 cubic meters per hour.
