1. What is the Centrifugal Pump Head Equation?

The centrifugal pump head equation calculates the total head developed by a pump, which is the sum of velocity head, pressure head, and elevation head. It's essential for determining the pump's capability to move fluid through a system.

2. How Does the Calculator Work?

The calculator uses the pump head equation:

Where:

• \( Velocity \) — Fluid velocity (m/s)
• \( g \) — Gravitational acceleration (9.81 m/s²)
• \( Pressure\ Head \) — Pressure energy per unit weight (m)
• \( Elevation \) — Height difference (m)

Explanation: The equation accounts for all forms of mechanical energy in the fluid system, converting them to equivalent height (head) in meters.

3. Importance of Head Calculation

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

4. Using the Calculator

Tips: Enter velocity in m/s, pressure head in meters of fluid, and elevation in meters. All values must be non-negative.

5. Frequently Asked Questions (FAQ)

Q1: What is velocity head?
A: Velocity head represents the kinetic energy of the fluid, converted to equivalent height (v²/2g).

Q2: How does elevation affect pump selection?
A: Higher elevation differences require pumps with greater head capacity to lift the fluid.

Q3: What are typical head values for centrifugal pumps?
A: Head values vary widely from 10m to several hundred meters depending on pump type and application.

Q4: Can this be used for viscous fluids?
A: This basic equation may need correction factors for highly viscous fluids.

Q5: How does pipe diameter affect the calculation?
A: Pipe diameter affects velocity (v = Q/A), which impacts the velocity head component.
