1. What is a Head to PSI Calculator?

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

Purpose: It helps engineers, plumbers, and technicians determine the static water pressure based on elevation head.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( P_{psi} \) — Pressure in pounds per square inch (psi)
• \( h_{ft} \) — Head height in feet (ft)
• 0.433 — Conversion factor (psi per foot of water)

Explanation: The head height is multiplied by 0.433 to convert feet of water column to psi.

3. Importance of Head to PSI Conversion

Details: Accurate pressure calculations are essential for designing water systems, sizing pipes, and selecting pumps.

4. Using the Calculator

Tips: Simply enter the head height in feet. The value must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What is the 0.433 conversion factor?
A: It represents the pressure exerted by 1 foot of water column (0.433 psi/ft at 4°C).

Q2: Does temperature affect the conversion?
A: Slightly - water density changes with temperature, but 0.433 is accurate for most practical applications.

Q3: Can I use this for other liquids?
A: No, this is specific to water. For other liquids, multiply by their specific gravity.

Q4: Is this static or dynamic pressure?
A: This calculates static pressure only. Dynamic pressure would include flow velocity effects.

Q5: How accurate is this calculation?
A: It's accurate for most engineering purposes, with less than 1% error under normal conditions.
