What is NPSH ? | what is NPSHa and NPSHr ? | Net Positive Suction Head

Ever wondered how pumps work and why NPSH (Net Positive Suction Head) is crucial for their smooth operation? In this video, we break down the concept of NPSH in a simple and easy-to-understand manner.
Pumps, like straws, create suction to draw fluid in and push it out. NPSH is like the “force” available at the suction side of the pump. It’s critical for preventing cavitation, which can damage pumps over time.
We discuss:
• NPSH Available (NPSHa): The pressure available at the pump’s suction side.
• NPSH Required (NPSHr): The minimum pressure needed to keep fluid moving smoothly.
• Calculating NPSHA: Static head + velocity head + pressure head - Vapour pressure.
Understanding NPSH is essential for engineers and operators to ensure pumps operate reliably and efficiently. Watch now to learn more about this fundamental concept in pump design and operation!
