Water Pressure Formula:
| From: | To: |
Water pressure calculation determines the pressure exerted by a column of water at a certain depth or height. It's based on the fundamental principle of hydrostatic pressure in fluid mechanics.
The calculator uses the water pressure formula:
Where:
Explanation: The pressure at any point in a fluid at rest is proportional to the density of the fluid, gravitational acceleration, and the height of the fluid column above that point.
Details: Accurate water pressure calculation is crucial for designing water supply systems, dams, underwater structures, and various engineering applications involving fluid dynamics.
Tips: Enter water density in kg/m³ (1000 for pure water), gravitational acceleration in m/s² (9.81 on Earth), and height in meters. All values must be positive.
Q1: What is the standard density of water?
A: The density of pure water at 4°C is approximately 1000 kg/m³. Density varies slightly with temperature and impurities.
Q2: How does gravity affect water pressure?
A: Gravity is a fundamental component of the pressure calculation. Higher gravitational acceleration results in greater pressure for the same fluid column height.
Q3: Does this formula work for other liquids?
A: Yes, the formula works for any fluid. You just need to use the correct density value for the specific fluid you're calculating pressure for.
Q4: How does water pressure change with depth?
A: Water pressure increases linearly with depth. For every meter of depth, pressure increases by approximately 9.81 kPa in fresh water.
Q5: What are common units for water pressure?
A: Common units include Pascals (Pa), kilopascals (kPa), atmospheres (atm), bars, and pounds per square inch (psi). This calculator uses Pascals.
