Calculate required horsepower for pump operation
📖 Pump Horsepower
Pump horsepower is the power required to pump a fluid at a given flow rate against a specific head. It depends on flow rate, head, fluid density, and pump efficiency.

💡 Tips & Information
- Horsepower is typically measured in HP or kW
- Formula: HP = (Q × H × ρ × g) / (η × 745.7), where Q is flow, H is head, ρ is density, g is gravity, η is efficiency
- Water density is approximately 1000 kg/m³
- Typical pump efficiency ranges from 50-85%
- Always add safety margin when selecting pump motor size
