Head Pressure Formula:
| From: | To: |
Head pressure, also known as hydrostatic pressure, is the pressure exerted by a fluid at rest due to the force of gravity. It increases with depth and is calculated using the formula P = ρ × g × h, where ρ is fluid density, g is gravitational acceleration, and h is the height of the fluid column.
The calculator uses the head pressure formula:
Where:
Explanation: The pressure at any point in a fluid at rest depends on the depth of that point, the density of the fluid, and the gravitational acceleration.
Details: Calculating head pressure is essential in various engineering applications including water supply systems, hydraulic engineering, tank design, and fluid mechanics. It helps determine the pressure at different depths in containers, pipes, and reservoirs.
Tips: Enter fluid density in kg/m³, gravitational acceleration in m/s² (default is Earth's gravity 9.8 m/s²), and height of fluid column in meters. All values must be positive numbers.
Q1: What units should I use for the inputs?
A: Use kg/m³ for density, m/s² for gravity, and meters for height. The result will be in Pascals (Pa).
Q2: Does this formula work for all fluids?
A: Yes, the formula works for any incompressible fluid at rest. You just need to input the correct density value for your specific fluid.
Q3: What is the standard value for gravitational acceleration?
A: On Earth, the standard value is approximately 9.8 m/s², though it varies slightly depending on location and altitude.
Q4: Can I use this calculator for gases?
A: This formula is primarily for liquids. For gases, additional factors like compressibility need to be considered.
Q5: How does temperature affect the calculation?
A: Temperature affects fluid density. For accurate results, use the density value at the actual temperature of your application.
