1. What is Pump Head Pressure Calculation?

The pump head pressure calculation converts hydraulic head (in feet) to pressure (in psi) considering the fluid's specific gravity. This is essential for pump selection, system design, and performance analysis in fluid systems.

2. How Does the Calculator Work?

The calculator uses the pump head to pressure formula:

Where:

• \( Head \) — Pump head in feet (ft)
• \( 0.433 \) — Conversion factor from feet of water to psi
• \( SG \) — Specific gravity of the fluid (unitless)

Explanation: The conversion factor 0.433 represents the pressure exerted by one foot of water column at standard conditions. Specific gravity adjusts for fluids other than water.

3. Importance of Head Pressure Calculation

Details: Accurate head pressure calculation is crucial for proper pump selection, system design, energy efficiency optimization, and ensuring adequate pressure throughout the fluid system.

4. Using the Calculator

Tips: Enter head in feet and specific gravity (1.000 for water). All values must be positive numbers. For water systems, use SG = 1.000.

5. Frequently Asked Questions (FAQ)

Q1: What is the difference between head and pressure?
A: Head refers to the height of fluid column the pump can lift, while pressure is the force per unit area. They are related through fluid density.

Q2: Why is specific gravity important?
A: Specific gravity accounts for fluid density differences. Denser fluids require more pressure to achieve the same head.

Q3: What is the 0.433 conversion factor?
A: This factor converts feet of water column to psi: 1 ft water = 0.433 psi at standard conditions.

Q4: When should I use this calculation?
A: Use for pump sizing, system design, troubleshooting, and when converting between head and pressure specifications.

Q5: Are there limitations to this formula?
A: This assumes standard gravity and temperature. For precise engineering calculations, consider temperature effects on fluid density.
