1. What is Hydraulic Pressure?

Hydraulic pressure is the force per unit area exerted by a fluid on its container. In hydraulic systems, this pressure is used to transmit power and perform work.

2. How Does the Calculator Work?

The calculator uses the fundamental pressure formula:

Where:

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

Explanation: The pressure exerted by a hydraulic system is directly proportional to the applied force and inversely proportional to the area over which the force is distributed.

3. Importance of Pressure Calculation

Details: Accurate pressure calculation is crucial for designing safe and efficient hydraulic systems, ensuring proper component selection, and preventing system failures.

4. Using the Calculator

Tips: Enter force in Newtons and area in square meters. Both values must be positive numbers. The calculator will compute the pressure in Pascals.

5. Frequently Asked Questions (FAQ)

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

Q2: How does pressure affect hydraulic system performance?
A: Higher pressures allow more work to be done with smaller components, but require stronger materials and seals to contain the pressure.

Q3: What is Pascal's principle in hydraulics?
A: Pascal's principle states that pressure exerted anywhere in a confined incompressible fluid is transmitted equally in all directions.

Q4: What factors affect hydraulic pressure?
A: Pressure is affected by the applied force, piston area, fluid properties, system temperature, and any restrictions in the system.

Q5: How is pressure maintained in hydraulic systems?
A: Pressure is typically maintained by a pump that provides constant fluid flow, with relief valves to prevent over-pressurization.
