1. What is Discharge Head of Pump?

Discharge head represents the height to which a pump can raise a fluid vertically. It is a measure of the pressure energy imparted to the fluid by the pump, expressed in meters of fluid column.

2. How Does the Calculator Work?

The calculator uses the discharge head formula:

Where:

• \( Head \) — Discharge head (m)
• \( Pressure \) — Pressure (Pa)
• \( Density \) — Fluid density (kg/m³)
• \( g \) — Gravitational acceleration (m/s²)

Explanation: This formula converts pressure energy to equivalent height using the fluid's density and gravitational constant.

3. Importance of Discharge Head Calculation

Details: Accurate discharge head calculation is crucial for pump selection, system design, and ensuring proper fluid transport in piping systems.

4. Using the Calculator

Tips: Enter pressure in Pascals (Pa), density in kg/m³, and gravitational acceleration in m/s². Standard gravity is 9.81 m/s². All values must be positive.

5. Frequently Asked Questions (FAQ)

Q1: What is the relationship between pressure and head?
A: Head is the height of fluid column equivalent to the pressure. Higher pressure results in higher discharge head for the same fluid density.

Q2: How does fluid density affect discharge head?
A: For the same pressure, denser fluids will have lower discharge head because more energy is required to lift heavier fluids.

Q3: What is typical discharge head range for centrifugal pumps?
A: Typical discharge heads range from 10-200 meters, depending on pump design and application requirements.

Q4: Why is gravitational acceleration included?
A: Gravitational acceleration is needed to convert between pressure energy and potential energy (height).

Q5: Can this formula be used for all fluid types?
A: Yes, the formula applies to all Newtonian fluids. For non-Newtonian fluids, additional considerations may be needed.
