1. What is the Datum Height Using Piezometric Head Formula?

The Datum Height at Section 1 refers to the height of flow at a particular section in steady non-viscous flow systems. It is calculated using the piezometric head, fluid pressure, and specific weight of the liquid.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( Z_1 \) — Datum Height at Section 1 (Meter)
• \( P \) — Pressure of Fluid (Pascal)
• \( P_h \) — Piezometric Head (Meter)
• \( \gamma_f \) — Specific Weight of Liquid (N/m³)

Explanation: This formula calculates the datum height by subtracting the piezometric head from the fluid pressure and dividing by the specific weight of the liquid.

3. Importance of Datum Height Calculation

Details: Accurate datum height calculation is crucial for analyzing fluid flow systems, determining energy gradients, and designing efficient hydraulic systems in engineering applications.

4. Using the Calculator

Tips: Enter fluid pressure in Pascal, piezometric head in meters, and specific weight in N/m³. All values must be valid (specific weight > 0).

5. Frequently Asked Questions (FAQ)

Q1: What is piezometric head?
A: 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.

Q2: What is specific weight of liquid?
A: Specific weight of liquid refers to the weight per unit volume of that substance, measured in Newton per cubic meter (N/m³).

Q3: When is this formula applicable?
A: This formula is applicable for steady non-viscous flow conditions where energy losses due to friction are negligible.

Q4: What are typical units for these measurements?
A: Pressure is measured in Pascal, piezometric head in meters, specific weight in N/m³, and datum height in meters.

Q5: 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.
