1. What is Pressure Intensity For Bottom Edge Of Plane Surface?

Pressure Intensity For Bottom Edge Of Plane Surface refers to the pressure at a specific point (point 2) calculated using the specific weight of the liquid and the vertical depth below the free surface of the liquid.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( P_2 \) — Pressure at point 2 (Pascal)
• \( S \) — Specific Weight of Liquid in Piezometer (N/m³)
• \( h_2 \) — Vertical Depth below free surface (m)

Explanation: The pressure at any point in a fluid at rest 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. All 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, typically measured in N/m³.

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

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

Q4: Can this formula be used for compressible fluids?
A: This simple linear relationship is primarily valid for incompressible fluids. For compressible fluids, density changes with pressure must be considered.

Q5: What are typical units for pressure measurement?
A: Pressure is commonly measured in Pascals (Pa), but other units like psi, bar, or mmHg are also used in different contexts.
