Cylinder Displacement Formula:
| From: | To: |
Cylinder displacement refers to the volume of fluid displaced by a hydraulic cylinder during one complete stroke. It's a critical measurement in hydraulic systems design and performance analysis.
The calculator uses the cylinder volume formula:
Where:
Explanation: The formula calculates the volume of a cylinder by multiplying the area of the circular base (πr²) by the height (stroke length).
Details: Accurate displacement calculation is essential for hydraulic system design, pump selection, flow rate determination, and overall system efficiency analysis.
Tips: Enter the cylinder radius and stroke length in centimeters. Both values must be positive numbers. The calculator will compute the displacement volume in cubic centimeters.
Q1: What's the difference between displacement volume and swept volume?
A: In hydraulic contexts, these terms are often used interchangeably to refer to the volume of fluid displaced by a cylinder during one complete stroke.
Q2: How do I calculate for different units?
A: Convert all measurements to consistent units before calculation. For inches, the result will be in cubic inches; for meters, cubic meters, etc.
Q3: Does this calculation work for both single-acting and double-acting cylinders?
A: Yes, this calculates the volume for one chamber. Double-acting cylinders have displacement on both extend and retract strokes (though retract displacement may differ if rod diameter is significant).
Q4: How does rod diameter affect the calculation for double-acting cylinders?
A: The extend stroke uses the full piston area, while the retract stroke uses the annular area (piston area minus rod area).
Q5: Can I use diameter instead of radius?
A: Yes, but remember radius = diameter/2, so the formula becomes V = π × (d/2)² × h = π × d² × h / 4
