Boiler Feed Pump Sizing Guide
This calculator helps determine critical parameters for boiler feed pump selection:
- Flow Rate Calculation: Based on boiler capacity and water properties
- Power Requirements: Considering pressure and efficiency
- NPSH Analysis: Net Positive Suction Head calculations
- Velocity Checks: Pipe sizing validation
Key Formulas
| Parameter | Formula |
|---|
| Flow Rate | Q = m/(ρ × 3600) |
| Pump Power | P = (Q × ΔP × 100)/(3.6 × η) |
| Velocity | v = Q/A |
| NPSH Available | NPSHa = (Ps - Pv)/ρg + hs |
Typical Pump Specifications
| Capacity (m³/h) | Pressure (bar) | Power (kW) |
