Pressure to Head Formula:
From: | To: |
Definition: This calculator converts pressure in pounds per square inch (psi) to head in feet of water.
Purpose: It's commonly used in hydraulics, fluid mechanics, and engineering to relate pressure to equivalent water column height.
The conversion uses the formula:
Where:
Explanation: The factor 2.31 comes from the specific weight of water (1 psi = 2.31 feet of water head).
Details: This conversion is essential for designing water systems, pumps, and understanding pressure relationships in fluid systems.
Tips: Simply enter the pressure value in psi and the calculator will automatically compute the equivalent head in feet.
Q1: Why is the conversion factor 2.31?
A: It's derived from the specific weight of water (62.4 lb/ft³) and unit conversions (1 ft² = 144 in²).
Q2: Does this work for other liquids?
A: No, this is specific to water. For other liquids, you need to account for their specific gravity.
Q3: What's the practical use of this conversion?
A: It's used to determine pump head requirements, pressure vessel specifications, and pipe system designs.
Q4: How accurate is this conversion?
A: It's accurate for water at standard conditions (60°F). Temperature variations slightly affect the value.
Q5: What's the reverse conversion (feet to psi)?
A: To convert feet to psi, divide the head by 2.31 or multiply by 0.433.
