1. What is a Psi To Ft Calculator?

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

Purpose: It helps engineers and technicians determine the equivalent height of a fluid column that would produce a given pressure.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ h = \frac{P \times 144}{\rho \times g} \]

Where:

\( h \) — Head (feet)
\( P \) — Pressure (psi)
\( \rho \) — Density (slugs/ft³)
\( g \) — Gravity (32.2 ft/s²)
144 — Conversion factor (in² to ft²)

Explanation: The pressure is converted to pounds per square foot, then divided by the product of density and gravity.

3. Importance of Psi to Feet Conversion

Details: This conversion is essential in hydraulics, pump systems, and fluid mechanics to relate pressure to equivalent fluid height.

4. Using the Calculator

Tips: Enter the pressure in psi, fluid density (default 1.94 slugs/ft³ for water), and gravity (default 32.2 ft/s²). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: Why is 144 used in the calculation?
A: 144 converts square inches to square feet (1 ft² = 144 in²), since we're converting psi to pounds per square foot.

Q2: What's a typical density value for water?
A: Fresh water at standard conditions has a density of 1.94 slugs/ft³ or 62.4 lb/ft³.

Q3: When would I change the gravity value?
A: The standard is 32.2 ft/s², but you might adjust for extreme precision or non-Earth applications.

Q4: How accurate is this conversion?
A: Very accurate for static conditions with constant density fluids at known gravity.

Q5: Can I use this for any fluid?
A: Yes, as long as you know the fluid's density in slugs/ft³.
