Hydrostatic Pressure Equation:
| From: | To: |
Hydrostatic pressure is the pressure exerted by a fluid at equilibrium at a given point within the fluid, due to the force of gravity. It increases in proportion to depth measured from the surface because of the increasing weight of fluid exerting downward force from above.
The calculator uses the hydrostatic pressure equation:
Where:
Explanation: This equation calculates the lateral pressure exerted by a fluid on a vertical wall, taking into account the fluid's density, gravitational force, and the height of the fluid column.
Details: Accurate water pressure calculation is crucial for designing dams, retaining walls, water tanks, and other hydraulic structures to ensure structural integrity and safety.
Tips: Enter fluid density in kg/m³ (1000 for water), gravitational acceleration in m/s² (9.81 for Earth), and fluid height in meters. All values must be positive.
Q1: Why is there a 1/2 factor in the equation?
A: The 1/2 factor accounts for the triangular pressure distribution on a vertical wall, with zero pressure at the surface and maximum pressure at the bottom.
Q2: What is the standard density of water?
A: The density of pure water is approximately 1000 kg/m³ at 4°C, though it varies slightly with temperature and impurities.
Q3: How does water pressure change with depth?
A: Water pressure increases linearly with depth due to the increasing weight of the water column above the measurement point.
Q4: Are there limitations to this equation?
A: This equation assumes static fluid conditions, constant density, and a vertical wall. It may not account for dynamic forces, varying densities, or inclined surfaces.
Q5: Can this be used for other fluids besides water?
A: Yes, the equation works for any fluid as long as you use the correct density value for that specific fluid.
