Formulas Used
Hydraulic Power
Phyd = (ρ × g × Q × H) / 3600
Where:
- ρ = Density of fluid (kg/m³)
- g = Gravity (9.81 m/s²)
- Q = Flow rate (m³/h)
- H = Head (m)
Pump Efficiency
η = (Phyd / Pin) × 100%
Where:
- Phyd = Hydraulic power (kW)
- Pin = Power input (kW)
Specific Speed
Ns = (N × √Q) / H3/4
Where:
- N = Speed (RPM)
- Q = Flow rate (m³/s)
- H = Head (m)
NPSH Required
NPSHr = (U2 × k) / (2 × g)
Where:
- U = Impeller peripheral velocity (m/s)
- k = Pump-specific coefficient
- g = Gravity (9.81 m/s²)
