Pressure to Head Formula (for water):
From: | To: |
Definition: This calculator converts pressure in pounds per square inch (psi) to head (height of water column) in feet.
Purpose: It's essential for hydraulic engineering, plumbing, and water system design to understand the relationship between pressure and water column height.
The calculator uses the formula:
Where:
Explanation: The conversion factor comes from the relationship between pressure and the height of a water column (1 psi = 2.31 ft of water at 60°F).
Details: Understanding this conversion helps in designing water systems, calculating pump requirements, and troubleshooting pressure issues in pipelines.
Tips: Simply enter the pressure value in psi to get the equivalent height of water column in feet. The value must be > 0.
Q1: Why is the conversion factor 2.31?
A: It's derived from the specific weight of water (0.433 psi/ft). The inverse (1/0.433) gives 2.31 ft/psi.
Q2: Does this work for other liquids?
A: No, this is specific to water. For other liquids, you need to consider their specific gravity.
Q3: Does temperature affect the conversion?
A: Slightly, as water density changes with temperature, but 2.31 is accurate enough for most practical applications.
Q4: How is this used in plumbing?
A: It helps determine if pressure is adequate for building height or if booster pumps are needed.
Q5: What's the relationship to water towers?
A: Water towers use height to create pressure - every 2.31 feet of elevation provides 1 psi of pressure.
