1. What is Pressure to Pump Head Conversion?

The pressure to pump head conversion calculates the equivalent height (head) that a pump can raise a fluid based on the pressure it generates. This is essential for designing and selecting pumps in fluid systems.

2. How Does the Calculator Work?

The calculator uses the fundamental equation:

Where:

• \( H \) — Pump head (meters)
• \( P \) — Pressure (Pascals)
• \( \rho \) — Fluid density (kg/m³, 1000 for water)
• \( g \) — Gravitational acceleration (9.81 m/s²)

Explanation: The equation converts pressure energy to potential energy by considering the fluid's density and gravity.

3. Importance of Pump Head Calculation

Details: Pump head is crucial for determining if a pump can overcome system resistance and deliver fluid to the required height in piping systems, HVAC, and water supply networks.

4. Using the Calculator

Tips: Enter pressure in Pascals, fluid density in kg/m³ (1000 for water), and gravitational acceleration (9.81 m/s² on Earth). All values must be positive.

5. Frequently Asked Questions (FAQ)

Q1: Why convert pressure to head?
A: Pump performance curves are typically expressed in head (meters) rather than pressure, making this conversion essential for pump selection.

Q2: What's the default density value?
A: The calculator defaults to 1000 kg/m³ (water at standard conditions). Adjust for other fluids.

Q3: Can I use different units?
A: The calculator uses SI units (Pa, kg/m³, m/s²). Convert other units before calculation.

Q4: Does this work for all fluids?
A: Yes, but you must input the correct density for your specific fluid.

Q5: What about viscous fluids?
A: This is a basic calculation. For viscous fluids, additional factors may need consideration.
