| Summary: | Most centrifugal pumps with low specific speed are designed using the method of increasing the flow rate; by this, each designer selects different flow rate amplification coefficients for the pumps. These different amplification coefficients lead to differences between the optimum conditions after amplification and the optimum design conditions, and thus, these factors lead to differences in the conversion coefficients of centrifugal pumps as hydraulic turbines. The conversion relation of the centrifugal pump as a hydraulic turbine based on the amplification coefficient was obtained through research, and this conversion relation can be used to the model selection of all hydraulic turbines.
