1. What is Hydraulic Pressure?

Hydraulic pressure is the force per unit area exerted by a fluid on a surface. In hydraulic systems, it's typically measured in pounds per square inch (PSI) and is fundamental to the operation of hydraulic cylinders and systems.

2. How Does the Calculator Work?

The calculator uses the basic pressure formula:

Where:

• \( PSI \) — Pressure in pounds per square inch
• \( Force \) — Applied force in pounds (lbs)
• \( Area \) — Surface area in square inches (in²)

Explanation: The pressure exerted by a hydraulic cylinder is directly proportional to the force applied and inversely proportional to the piston area.

3. Importance of Hydraulic Pressure Calculation

Details: Accurate pressure calculation is crucial for designing hydraulic systems, selecting appropriate components, and ensuring safe operation within pressure limits.

4. Using the Calculator

Tips: Enter force in pounds and area in square inches. Both values must be positive numbers. The calculator will compute the resulting pressure in PSI.

5. Frequently Asked Questions (FAQ)

Q1: What is a typical operating pressure for hydraulic systems?
A: Most industrial hydraulic systems operate between 1500-3000 PSI, though some specialized systems may go higher.

Q2: How do I calculate the area of a hydraulic cylinder?
A: For a circular piston, area = π × (radius)² or π × (diameter)²/4. Radius/diameter should be in inches for PSI calculation.

Q3: What's the difference between PSI and Pascals?
A: PSI is pounds per square inch (imperial), while Pascals are Newtons per square meter (metric). 1 PSI ≈ 6895 Pa.

Q4: Why is hydraulic pressure important?
A: It determines the force output of cylinders, affects component sizing, and must be kept within safe limits to prevent system failure.

Q5: Can I use this for pneumatic systems?
A: Yes, the same formula applies to gas pressure, though pneumatic systems typically operate at much lower pressures (80-150 PSI).
