1. What is Piezometric Head?

Piezometric Head refers to the specific measurement of liquid pressure above a vertical datum, typically measured as the elevation of the liquid surface at the entrance of a piezometer. It represents the total head in a fluid flow system.

2. How Does the Calculator Work?

The calculator uses the Piezometric Head formula:

Where:

• \( P \) — Piezometric Head (Meter)
• \( Ph \) — Pressure of Fluid (Pascal)
• \( \gamma_f \) — Specific Weight of Liquid (N/m³)
• \( h \) — Height of Section (Meter)

Explanation: The formula calculates the piezometric head by dividing the fluid pressure by the specific weight of the liquid and adding the height of the section.

3. Importance of Piezometric Head Calculation

Details: Accurate piezometric head calculation is crucial for analyzing fluid flow systems, designing hydraulic structures, and understanding pressure distribution in steady non-viscous flows.

4. Using the Calculator

Tips: Enter fluid pressure in Pascal, specific weight in N/m³, and height in meters. All values must be valid positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is the difference between piezometric head and pressure head?
A: Piezometric head is the sum of pressure head and elevation head, representing the total energy per unit weight of fluid.

Q2: When is this formula applicable?
A: This formula is specifically designed for steady non-viscous flow conditions where energy losses are negligible.

Q3: What are typical units for these measurements?
A: Pressure is measured in Pascal, specific weight in N/m³, and both head and height in meters.

Q4: Can this calculator be used for compressible fluids?
A: This formula is primarily designed for incompressible fluids. For compressible fluids, additional factors need to be considered.

Q5: How accurate is this calculation?
A: The calculation provides theoretical values based on ideal conditions. Actual measurements may vary due to fluid viscosity and other real-world factors.
