Issues regarding the selection and power of circulating water pumps

There is one thing that is unclear. Suppose there is an existing closed-loop system with a rated flow rate of 500 t/h, and the total head loss at this flow rate is 15 m. However, when selecting the water pump now, one was chosen with a rated flow rate of 500 t/h and a rated head of 30 m. May I ask, by how much is the blade efficiency of the water pump lower than its rated value under rated operating conditions? Why?

Is there no one? . . . . . . . .
