Pump Suction Specific Speed
Many times we come across the term pump suction specific speed (Nsss) during design and pump selection stages. If you wonder why this term most widely used in pump design or selection, then this article will help you to understand it. Suction Specific Speed It's a dimensionless number and index relating the flow, Net Positive Suction Head required (NPSHr) and speed for pumps. … [Read more...]
Centrifugal Pump System Curve and Pump Operating Point
In this article, we will see the Centrifugal Pump System Curve and Pump Operating Point. The system curve is a very basic element to finalizing the pump operating point ie., flow and head requirement. Pump System Curve Pump system curve represents the resistance offered by the system ie., the pressure developed by the pump is high enough to overcome the resistance offered by … [Read more...]
Centrifugal Compressor Surge Basics, Mechanism
In this article, we will see the centrifugal compressor surge-Basics, mechanism and also we will see how the surge takes place in centrifugal compressor with an example. Surge Surge is a characteristic behaviour of a centrifugal compressor that can occur when inlet flow reduced such that the head developed by the compressor is insufficient to overcome the pressure at the … [Read more...]
