1. What is the Output Power of Centrifugal Pump?

The Output Power of Centrifugal Pump is the power available at the output of the centrifugal pump. It represents the useful power delivered by the pump to the fluid being pumped.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ OP = \frac{w \times Q \times H_m}{1000} \]

Where:

\( OP \) — Output Power of Centrifugal Pump (kW)
\( w \) — Specific Weight of Fluid in Pump (N/m³)
\( Q \) — Actual Discharge at Centrifugal Pump Outlet (m³/s)
\( H_m \) — Manometric Head of Centrifugal Pump (m)

Explanation: The formula calculates the output power by multiplying the specific weight of the fluid, the actual discharge rate, and the manometric head, then dividing by 1000 to convert to kilowatts.

3. Importance of Output Power Calculation

Details: Accurate output power calculation is crucial for determining pump efficiency, sizing appropriate motors, and ensuring optimal pump performance in various fluid transport applications.

4. Using the Calculator

Tips: Enter specific weight in N/m³, actual discharge in m³/s, and manometric head in meters. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is specific weight of fluid?
A: Specific weight is the weight per unit volume of a fluid, typically measured in N/m³. It equals density multiplied by gravitational acceleration.

Q2: How is actual discharge different from theoretical discharge?
A: Actual discharge accounts for real-world factors like leakage and efficiency losses, while theoretical discharge is based on ideal conditions.

Q3: What is manometric head?
A: Manometric head is the total head against which the centrifugal pump has to work, including static, velocity, and pressure heads.

Q4: Why divide by 1000 in the formula?
A: The division by 1000 converts the result from watts to kilowatts (1 kW = 1000 W).

Q5: What are typical output power ranges for centrifugal pumps?
A: Output power can range from fractional kilowatts for small pumps to several megawatts for large industrial pumps, depending on application requirements.
