Water Pressure Equation:
| From: | To: |
The water pressure calculation from an elevated tank uses the hydrostatic pressure formula to determine the pressure at the bottom of a water column. This is essential for designing water supply systems, understanding fluid behavior, and ensuring proper water distribution.
The calculator uses the hydrostatic pressure equation:
Where:
Explanation: The equation calculates the pressure exerted by a column of fluid due to gravity, which increases linearly with depth.
Details: Accurate water pressure calculation is crucial for designing water supply systems, determining pump requirements, ensuring adequate water flow, and maintaining system safety in various engineering applications.
Tips: Enter water density in kg/m³ (typically 1000 for pure water), gravity in m/s² (typically 9.81 on Earth), and height in meters. All values must be positive numbers.
Q1: What is the typical density value for water?
A: Pure water at 4°C has a density of 1000 kg/m³. This value changes slightly with temperature and impurities.
Q2: Does this calculation work for other fluids?
A: Yes, the same formula applies to any fluid, but you must use the correct density value for that specific fluid.
Q3: How does temperature affect water pressure calculations?
A: Temperature affects water density. Warmer water is less dense, which slightly reduces the pressure for the same height.
Q4: What are common units for water pressure?
A: Pascals (Pa) are the SI unit, but other common units include psi, bar, and meters of water column.
Q5: Is atmospheric pressure included in this calculation?
A: No, this formula calculates only the hydrostatic pressure. Total pressure would include atmospheric pressure added to the hydrostatic pressure.
