How to Use the Water Pressure Calculator

A Water Pressure Calculator determines the pressure exerted by a column of water based on its height, density, and gravitational force, using the formula P = ρgh.

What It Does:

This tool helps engineers, students, plumbers, and DIYers estimate the pressure in a static column of water. It’s useful in fluid mechanics, water supply systems, and hydrostatic calculations.

Steps to Use:

1. Enter the height of the water column in meters (e.g., height from the water surface to the outlet).
2. Enter the water density in kg/m³ (1000 is the default for fresh water).
3. Enter gravitational acceleration in m/s² (default is 9.81 on Earth).

Then click "Calculate Pressure" to see the pressure in Pascals (Pa).

Formula Used:

diffCopiarEditarP = ρ × g × h
Where:
- P = Pressure (Pa)
- ρ = Density (kg/m³)
- g = Gravity (m/s²)
- h = Height (m)

Water Pressure Calculator FAQ

Q1: What does this calculator measure?
A: It calculates hydrostatic pressure—the pressure exerted by a column of water at a specific depth.

Q2: What units are used in this calculator?
A: Height in meters, density in kg/m³, gravity in m/s², and output pressure in Pascals (Pa).

Q3: What is the typical density of water?
A: Freshwater is approximately 1000 kg/m³ at room temperature.

Q4: Can I change gravity for different planets?
A: Yes! Just input a different value. For example, Moon's gravity is about 1.62 m/s².

Q5: Does this account for flowing water or pipe pressure loss?
A: No. This is for static pressure only (not dynamic pressure or losses due to friction or elevation in piping).
