1. What is a Pump Head to PSI Calculator?

Definition: This calculator converts pump head in feet to pressure in pounds per square inch (psi) using the fluid's specific gravity.

Purpose: It helps engineers, technicians, and maintenance personnel quickly convert between these common pump measurement units.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( P_{psi} \) — Pressure in pounds per square inch (psi)
• \( h_{ft} \) — Pump head in feet (ft)
• \( SG \) — Specific gravity of the fluid (dimensionless)
• 0.433 — Conversion factor (psi per foot of water)

Explanation: The formula converts the energy imparted by the pump (head) to the resulting pressure, accounting for the fluid's density.

3. Importance of Pump Head to PSI Conversion

Details: Understanding this conversion is crucial for system design, pump selection, and troubleshooting hydraulic systems.

4. Using the Calculator

Tips: Enter the pump head in feet and the fluid's specific gravity (default 1.0 for water). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What is pump head?
A: Pump head is a measurement of the energy a pump adds to the fluid, expressed in feet of fluid column.

Q2: Why 0.433 in the formula?
A: This is the conversion factor representing the pressure exerted by 1 foot of water (0.433 psi/ft).

Q3: What's a typical specific gravity value?
A: Water at standard conditions has SG=1.0. Other fluids vary (e.g., gasoline ~0.7, seawater ~1.03).

Q4: Does this work for any fluid?
A: Yes, as long as you know the fluid's specific gravity relative to water.

Q5: How accurate is this conversion?
A: Very accurate for most engineering purposes, assuming constant fluid density.
