In liquid-handling turbomachines (pumps), local pressure drops can cause the fluid to vaporize, creating vapor bubbles that collapse violently. This phenomenon, known as , destroys blade materials. NPSH Available ( NPSHAcap N cap P cap S cap H sub cap A ): Must always be greater than the NPSH Required ( NPSHRcap N cap P cap S cap H sub cap R ) specified by the manufacturer to prevent cavitation. 5.

. Mastering velocity triangles is critical for predicting pressure rises, fluid deflections, and overall machine efficiency. 2. Classification of Turbomachinery
: Machines like steam or wind turbines extract energy from the fluid. Power Absorbing
