Net Positive Suction Head (NPSH) | Cavitation in Pumps | Chemical Engineering #FluidMechanics
Ever wondered why pumps sometimes make noise or fail? It could be due to cavitation! Learn what Net Positive Suction Head (NPSH) means and why it's crucial in pump design. 🔹 NPSHa = Net Positive Suction Head Available 🔹 NPSHr = Net Positive Suction Head Required If NPSHa is less than NPSHr → Cavitation occurs! Avoid pump failure by ...

NPSH and Pump Selection
*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 *
