1. What is Gravity Fed Water Pressure?

Definition: This calculator determines the static water pressure at the bottom of a column of water due to gravity.

Purpose: It helps engineers, plumbers, and homeowners calculate water pressure in tanks, wells, and plumbing systems.

2. How Does the Calculator Work?

The calculator uses the hydrostatic pressure formula:

Where:

• \( P \) — Water pressure (Pascals)
• \( \rho \) — Water density (typically 1000 kg/m³)
• \( g \) — Gravitational acceleration (9.81 m/s²)
• \( h \) — Height of water column (meters)

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

3. Importance of Water Pressure Calculation

Details: Proper pressure calculation ensures adequate water flow, prevents pipe damage, and helps design efficient water systems.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

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

Q2: Does this account for atmospheric pressure?
A: No, this calculates only the hydrostatic pressure. Total pressure would add atmospheric pressure (101325 Pa at sea level).

Q3: How does height affect pressure?
A: Pressure increases by about 9.81 kPa for every meter of height (with ρ=1000 kg/m³).

Q4: Can I use this for other liquids?
A: Yes, but you must use the correct density (ρ) for the specific liquid.

Q5: How do I convert Pascals to PSI?
A: 1 psi ≈ 6894.76 Pa. Divide the Pascal value by 6894.76 to get PSI.
