PSI to Feet of Water Formula:
| From: | To: |
The PSI to feet of water conversion calculates the height of a water column that would produce a given pressure. This is particularly useful in hydraulics, plumbing, and engineering applications where pressure measurements need to be converted to equivalent water column height.
The calculator uses the conversion formula:
Where:
Explanation: The conversion factor 2.31 comes from the fact that 1 PSI equals the pressure exerted by a column of water 2.31 feet high.
Details: This conversion is essential in various engineering fields, particularly in hydraulics, water supply systems, irrigation, and pump design where pressure measurements need to be expressed as equivalent water column height.
Tips: Enter the pressure value in PSI (pounds per square inch). The value must be greater than zero. The calculator will automatically compute the equivalent head in feet of water.
Q1: Why is the conversion factor approximately 2.31?
A: The exact conversion is 1 PSI = 2.306 feet of water at 4°C, but 2.31 is commonly used as a standard approximation in engineering calculations.
Q2: Does temperature affect the conversion?
A: Yes, water density changes with temperature, which slightly affects the conversion. The 2.31 factor is based on water at approximately 4°C (39.2°F).
Q3: Can this conversion be used for other liquids?
A: No, this specific conversion factor is only valid for water. Other liquids would require different conversion factors based on their specific gravity.
Q4: What are common applications of this conversion?
A: Common applications include pump head calculations, water tower design, pipeline pressure analysis, and irrigation system planning.
Q5: How accurate is this conversion for engineering purposes?
A: The 2.31 conversion factor is sufficiently accurate for most engineering applications, though precise calculations might use 2.306 for greater accuracy.
