1. What is a Water Pressure Head Height Calculator?

Definition: This calculator determines the water pressure at a certain depth based on the hydrostatic pressure formula.

Purpose: It helps engineers, plumbers, and fluid system designers calculate pressure from water column height.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( P \) — Water pressure (Pascals)
• \( \rho \) — Water density (kg/m³)
• \( g \) — Gravitational acceleration (m/s²)
• \( h \) — Head height (meters)

Explanation: The pressure increases linearly with depth due to the weight of the water above.

3. Importance of Water Pressure Calculation

Details: Accurate pressure calculations are essential for designing water systems, dams, pipelines, and hydraulic equipment.

4. Using the Calculator

Tips: Enter water density (default 1000 kg/m³), gravity (default 9.81 m/s²), and head height in meters. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What's the standard water density value?
A: Pure water at 4°C has a density of 1000 kg/m³. This decreases slightly with temperature increase.

Q2: Why is gravity included in the calculation?
A: Gravity determines the weight of the water column, which creates the pressure.

Q3: How does head height relate to pressure?
A: Every 1 meter of water height creates approximately 9810 Pa (9.81 kPa) of pressure.

Q4: Can this be used for other liquids?
A: Yes, but you must use the correct density value for the specific liquid.

Q5: How do I convert Pascals to other units?
A: 1 kPa = 1000 Pa, 1 bar ≈ 100 kPa, 1 psi ≈ 6895 Pa.
