Head Formula:
From: | To: |
Definition: This calculator converts pressure in pounds per square inch (psi) to head in feet of water.
Purpose: It helps engineers, plumbers, and fluid system designers convert between pressure and head measurements.
The calculator uses the formula:
Where:
Explanation: The conversion factor 2.31 comes from the relationship between pressure and the height of a water column (1 psi = 2.31 ft of water head).
Details: This conversion is essential in hydraulics, pump sizing, piping systems, and when working with pressure gauges and elevation differences.
Tips: Simply enter the pressure value in psi to get the equivalent head in feet of water.
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 besides water?
A: No, this is specific to water. For other liquids, you need to account for their specific gravity.
Q3: How accurate is this conversion?
A: It's accurate for water at standard conditions (60°F, 1 atm). Temperature and purity can slightly affect results.
Q4: When would I need to convert psi to feet of head?
A: Common applications include pump specifications, pipeline design, and when working with elevation differences in fluid systems.
Q5: What's the difference between pressure and head?
A: Pressure is force per unit area (psi), while head represents the height of a fluid column that would produce that pressure.
