Water Pressure Equation:
| From: | To: |
The water pressure calculation determines the pressure exerted by a column of water in a storage tank. This is based on the fundamental hydrostatic pressure equation and is essential for designing water supply systems, plumbing, and storage tanks.
The calculator uses the hydrostatic pressure equation:
Where:
Explanation: The equation calculates the pressure at the bottom of a water column based on the weight of the water above that point.
Details: Accurate water pressure calculation is crucial for designing efficient water supply systems, ensuring adequate pressure for appliances, preventing pipe damage from excessive pressure, and optimizing pump selection.
Tips: Enter water density in kg/m³ (typically 1000 for pure water), gravity in m/s² (typically 9.81 on Earth), and water column height in meters. All values must be positive.
Q1: What is the typical density value for water?
A: Pure water at 4°C has a density of 1000 kg/m³. This value decreases slightly with increasing temperature.
Q2: How does water pressure change with height?
A: Water pressure increases linearly with the height of the water column. Every meter of height adds approximately 9.81 kPa of pressure.
Q3: Why is gravity important in this calculation?
A: Gravity determines the weight of the water column, which directly affects the pressure exerted at the bottom.
Q4: Can this calculation be used for other liquids?
A: Yes, the same formula applies to any liquid, but you must use the correct density value for that specific liquid.
Q5: How does this relate to real-world water systems?
A: This calculation helps determine the static pressure in water towers, storage tanks, and elevated reservoirs, which is essential for municipal water supply planning.
