Introduction: Calculating pump shaft power is crucial for assessing the efficiency of a pump system. A dedicated calculator simplifies this process, offering accuracy and convenience. In this article, we’ll provide a functional code for a pump shaft power calculator, ensuring precision in calculations.

How to Use:

1. Enter the Flow Rate (Q) in cubic meters per second (m³/s).
2. Input the Total Head (H) in meters (m).
3. Specify the Pump Efficiency (η) as a percentage.
4. Click the “Calculate” button to obtain the Pump Shaft Power.

Formula: The pump shaft power (P) can be calculated using the following formula:

Where:

• Q is the flow rate,
• H is the total head,
• ρ is the fluid density,
• g is the acceleration due to gravity,
• η is the pump efficiency.

Example Solve: Let’s say we have a pump with a flow rate of 0.02 m³/s, a total head of 15 m, fluid density of 1000 kg/m³, and an efficiency of 80%.

P≈294.07Watts

FAQs: Q: What units should I use for flow rate and total head?

A: Flow rate should be in cubic meters per second (m³/s), and total head should be in meters (m).

Q: Is pump efficiency always in percentage form?

A: Yes, pump efficiency is typically expressed as a percentage.

Conclusion: Utilizing a pump shaft power calculator streamlines the assessment of pump efficiency. The provided ensures accurate calculations, making it a valuable tool for engineers and professionals in the field.
