1. What is Pump Head Pressure?

Pump head is the height to which a pump can raise a fluid, expressed in meters of fluid column. It represents the energy imparted to the fluid by the pump and is a key parameter in pump selection and system design.

2. How Does the Calculator Work?

The calculator uses the pump head formula:

\[ H = \frac{P}{\rho \times g} \]

Where:

Explanation: The equation converts pressure energy to equivalent height of fluid column, accounting for the fluid's density and gravitational acceleration.

3. Importance of Pump Head Calculation

Details: Accurate pump head calculation is essential for proper pump selection, system design, and ensuring the pump can overcome system losses and elevation differences.

4. Using the Calculator

Tips: Enter pressure in pascals (Pa), fluid density in kg/m³, and gravity (default is 9.81 m/s²). All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between head and pressure?
A: Head is independent of fluid density, while pressure depends on density. Head is useful for comparing pumps across different fluids.

Q2: What are typical pump head values?
A: Values vary widely by application - from a few meters for circulation pumps to hundreds of meters for high-pressure applications.

Q3: How does fluid density affect head?
A: Head calculation accounts for density - a denser fluid will produce less head for the same pressure.

Q4: When is this calculation most useful?
A: When you know the pressure generated by a pump and need to determine how high it can lift a specific fluid.

Q5: Can I use this for any fluid?
A: Yes, as long as you know the fluid's density. The calculation works for both liquids and gases.
