NPSH Calculator
Calculate Net Positive Suction Head for pump systems
📖 Net Positive Suction Head
NPSH is the total head at the suction port of a pump minus the vapor pressure head. It determines if a pump can operate without cavitation.
📊 Result
💡 Tips & Information
- NPSH is typically measured in meters (m) or feet (ft)
- NPSH Available must exceed NPSH Required to prevent cavitation
- Higher temperatures increase vapor pressure and reduce NPSH
- Add safety margin of 0.5-1.0 m above NPSH Required
- Cavitation causes noise, vibration, and pump damage
