Force Formula:
From: | To: |
Definition: This calculator converts pressure (psi) to force (pounds-force) when the area is known.
Purpose: It helps engineers, mechanics, and technicians determine the force exerted by fluid pressure or mechanical pressure on a given area.
The calculator uses the formula:
Where:
Explanation: The pressure is multiplied by the area to calculate the total force exerted over that area.
Details: This calculation is essential in hydraulic systems, pneumatic systems, structural engineering, and any application where pressure acts on a surface.
Tips: Enter the pressure in psi and the area in square inches. Both values must be greater than 0.
Q1: What's the difference between psi and lbf?
A: PSI (pounds per square inch) is pressure (force per unit area), while lbf (pounds-force) is a unit of force.
Q2: How do I find the area if I only know diameter?
A: For circular areas, use \( A = \pi \times r^2 \) where \( r \) is radius (diameter/2).
Q3: Can I use this for hydraulic cylinder force calculations?
A: Yes, this is exactly how hydraulic cylinder force is calculated (pressure × piston area).
Q4: What's a typical application for this calculation?
A: Determining the force exerted by a hydraulic press, calculating bolt tension from torque, or finding the load on a pressure vessel wall.
Q5: Does this account for friction or efficiency losses?
A: No, this calculates theoretical force. Actual systems may have lower force due to friction and efficiency factors.
