Pump Sizing Calculator
Pump sizing is essential in industrial plants, HVAC systems, chemical processing, water supply, firefighting systems, and hydraulic circuits. This Pump Sizing Tool calculates: 1. Total Dynamic Head (TDH), 2. Hydraulic Power, 3. Required Pump Power. Ideal for mechanical, chemical, instrumentation, and process engineers.
Calculate Pump Head & Power Requirement
Enter flow rate in m³/s.
Enter the total head (static + friction) in meters.
Enter pump efficiency as a decimal (e.g., 0.7 = 70%).
Click Calculate Pump Power.
The tool displays hydraulic and required pump power.
🧭 How to Use
FAQ
Q1. What is pump head?
A. The energy required to move fluid, expressed in meters of fluid column.
Q2. Does higher head mean more power?
A. Yes — pump power is directly proportional to head and flow rate.
Q3. What efficiency should I enter?
A. Use the manufacturer’s pump efficiency (typically 0.6–0.85).
Q4. Can this tool be used for any liquid?
A. Yes, but the calculation assumes water. For other liquids, density must be modified.
