Net Positive Suction Head Calculation
*Pump Cavitation Reasons ‼️✅ - *Low suction pressure*: Insufficient NPSH (Net Positive Suction Head) - *High fluid temperature*: Vapor pressure increases, causing cavitation - *Air or gas in the system*: Air pockets or entrained gas can cause cavitation - *Improper pump selection*: Wrong pump size or type for the application - *Clogged suction strainer or filter*: Restricts flow, causing low suction pressure - *Incorrect piping design*: Too many bends, elbows, or valves, causing pressure drops *
