Force Formula:
From: | To: |
Definition: This calculator determines the force output of a pneumatic cylinder based on air pressure and piston area.
Purpose: It helps engineers and technicians design and select appropriate pneumatic cylinders for mechanical systems.
The calculator uses the formula:
Where:
Explanation: The pressure applied to the piston area creates a linear force that moves the cylinder rod.
Details: Accurate force calculations ensure proper system operation, safety, and selection of appropriately sized components.
Tips: Enter the system pressure in Pascals and the piston area in square meters. Both values must be > 0.
Q1: How do I find the piston area?
A: For circular pistons, use \( A = \pi r^2 \) where r is the piston radius. For non-circular pistons, calculate the cross-sectional area.
Q2: What's a typical operating pressure?
A: Most industrial pneumatic systems operate between 400,000-700,000 Pa (4-7 bar), but always check your specific system specifications.
Q3: Does this account for friction losses?
A: No, this calculates theoretical force. Actual force may be 5-20% less due to friction and efficiency losses.
Q4: How do I convert to other units?
A: 1 N = 0.2248 lbf, 1 Pa = 1 N/m² = 0.000145 psi, 1 m² = 10.764 ft²
Q5: What about double-acting cylinders?
A: This calculates force in one direction. For double-acting cylinders, calculate separately for extend and retract strokes (different areas due to the rod).
