Water Height to PSI Formula:
| From: | To: |
The water height to PSI conversion calculates the pressure exerted by a column of water based on its height. This is based on the principle that every foot of water height creates approximately 0.433 psi of pressure at its base.
The calculator uses the simple formula:
Where:
Explanation: The conversion factor 0.433 comes from the density of water and gravitational acceleration, representing the pressure exerted by one foot of water column.
Details: This calculation is essential for hydraulic systems, plumbing design, water tower operations, irrigation systems, and understanding fluid mechanics in various engineering applications.
Tips: Enter the water height in feet. The value must be positive. The calculator will instantly compute the corresponding pressure in PSI.
Q1: Why is the conversion factor 0.433?
A: This factor is derived from the density of water (62.4 lb/ft³) divided by 144 (square inches in a square foot): 62.4 ÷ 144 = 0.433 psi per foot.
Q2: Does this work for saltwater or other liquids?
A: No, this calculation is specific to fresh water. Saltwater and other liquids have different densities and would require different conversion factors.
Q3: What are typical water pressure values in residential systems?
A: Most residential water systems operate between 40-80 psi, with 50-60 psi being ideal for most applications.
Q4: How accurate is this calculation?
A: This provides a good estimate for practical purposes, but exact values may vary slightly due to temperature, water purity, and atmospheric conditions.
Q5: Can this be used for water tower design?
A: Yes, this calculation is fundamental for determining the pressure available from water towers based on their height above ground level.
