Head Pressure Formula:
| From: | To: |
Head pressure refers to the pressure exerted by a column of liquid due to its height. In tank systems, it represents the static pressure at the bottom of the tank caused by the weight of the water above.
The calculator uses the head pressure formula:
Where:
Explanation: The head pressure in meters of water column is equal to the height of the water column. This simple relationship holds true for water at standard conditions.
Details: Calculating head pressure is essential for designing water systems, selecting appropriate pumps, ensuring proper flow rates, and determining pressure requirements in various industrial and domestic applications.
Tips: Enter the water height in meters. The value must be non-negative. The calculator will compute the corresponding head pressure.
Q1: Does this calculation work for fluids other than water?
A: The formula H = h is specific to water. For other fluids, you would need to account for different densities using the formula P = ρgh, where ρ is the fluid density.
Q2: What are typical head pressure values in residential water systems?
A: Typical values range from 10-50 meters (approximately 14-70 psi) depending on the system design and local regulations.
Q3: How does tank shape affect head pressure?
A: Head pressure depends only on height, not on the shape or volume of the tank. The pressure at the bottom is determined solely by the height of the fluid column above it.
Q4: Is this the same as pressure in psi or other units?
A: No, this calculation gives head pressure in meters of water column. To convert to psi, multiply by 1.42 (approximately) or use P = 0.433 × h for psi directly.
Q5: Does temperature affect head pressure calculations?
A: Temperature affects water density slightly, but for most practical applications, the effect is negligible in head pressure calculations.
