What is pump specific speed?

The specific speed is an index used to predict the desired performance of the pump or turbine. In other words, it offers the general form of a pump pusher. This is the form of pusher that offers its flow and head characteristics, so that the designer can then select a pump or turbine more suitable for a given application.Predicting desired pump or turbine performance can be done with specific speed. It's possible that it's possible that it's possible that it's possible that it's possible that it's possible that it's possible that it's possible that it's possible that it's possible that it's possible that it's It predicts the shape of the pump. The shape of the impeller predicts its flow and head characteristics so that the designer can choose a pump or turbine most appropriate for a particular application.
