1. What is a Water Height to PSI Calculator?

Definition: This calculator converts water column height in feet to pressure in pounds per square inch (psi).

Purpose: It helps engineers, plumbers, and technicians determine water pressure based on elevation differences in water systems.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ P_{psi} = h_{ft} \times 0.433 \]

Where:

Explanation: The formula converts the weight of a column of water into pressure at its base.

3. Importance of Water Pressure Calculation

Details: Accurate pressure calculations are essential for designing water systems, ensuring proper pump selection, and maintaining system safety.

4. Using the Calculator

Tips: Simply enter the height of the water column in feet. The value must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: Why is the conversion factor 0.433?
A: This represents the pressure exerted by 1 foot of water (0.433 psi/ft) at standard conditions.

Q2: Does this work for any liquid?
A: No, this is specific to water. Other liquids would require different conversion factors based on their density.

Q3: How accurate is this calculation?
A: It's accurate for pure water at standard temperature (4°C/39.2°F). Temperature variations can cause slight deviations.

Q4: What's the pressure at 100 feet of water?
A: Approximately 43.3 psi (100 × 0.433).

Q5: How does this relate to head pressure in pumps?
A: Pump head is often measured in feet of water - this calculation converts it to psi for system design.
