1. What is Hydraulic Pressure?

Hydraulic pressure is the force per unit area exerted by a fluid on the walls of its container or on a surface. In hydraulic systems, this pressure is used to transmit power through fluids.

2. How Does the Calculator Work?

The calculator uses the fundamental pressure equation:

Where:

• \( P \) — Pressure in Pascals (Pa)
• \( F \) — Force in Newtons (N)
• \( A \) — Area in square meters (m²)

Explanation: The equation shows that pressure increases with greater force or smaller surface area.

3. Importance of Pressure Calculation

Details: Accurate pressure calculation is crucial for designing hydraulic systems, ensuring proper operation of cylinders, and maintaining system safety.

4. Using the Calculator

Tips: Enter force in Newtons and area in square meters. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What are common units for hydraulic pressure?
A: While Pascals are SI units, hydraulic systems often use bar (1 bar = 100,000 Pa) or psi (pounds per square inch).

Q2: How does piston diameter affect pressure?
A: Pressure decreases with larger piston area (diameter²) for the same force, following the inverse relationship in the equation.

Q3: What's typical operating pressure for hydraulic systems?
A: Industrial systems often operate between 150-300 bar, while mobile equipment might use 200-350 bar.

Q4: How does fluid viscosity affect pressure?
A: While this calculator shows static pressure, viscosity affects dynamic pressure losses in hydraulic lines.

Q5: What safety factors should be considered?
A: Always design for pressures higher than operating pressure, typically with a safety factor of 1.5-4x.
