1. What is Pressure Intensity for Top Edge of Plane Surface?

Pressure Intensity for Top Edge of Plane Surface refers to the pressure at a specific point on a plane surface, calculated using the specific weight of the liquid and the vertical depth below the free surface.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( P1 \) — Pressure at given point 1 (Pa)
• \( S \) — Specific Weight of Liquid in Piezometer (N/m³)
• \( h1 \) — Vertical Depth below free surface (m)

Explanation: The pressure intensity at any point in a static fluid is directly proportional to the specific weight of the fluid and the vertical depth below the free surface.

3. Importance of Pressure Intensity Calculation

Details: Accurate pressure calculation is crucial for designing hydraulic systems, analyzing fluid behavior in containers, and ensuring structural integrity in fluid mechanics applications.

4. Using the Calculator

Tips: Enter specific weight in N/m³ and vertical depth in meters. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is specific weight of a liquid?
A: Specific weight is the weight per unit volume of a substance, measured in N/m³.

Q2: How does pressure vary with depth?
A: Pressure increases linearly with depth in a static fluid due to the weight of the fluid above.

Q3: What is the difference between pressure and pressure intensity?
A: Pressure intensity refers to the pressure at a specific point, while pressure is a more general term for force per unit area.

Q4: Does this formula work for all fluids?
A: Yes, this fundamental hydrostatic pressure formula works for all incompressible fluids at rest.

Q5: How accurate is this calculation?
A: The calculation is exact for static, incompressible fluids under constant gravitational acceleration.
