Now I have made a Bernoulli equation to calculate the outlet flow of the centrifugal pump, but how to calculate the work provided by the pump? In addition, what does the power on the centrifugal pump nameplate mean?

You need to calculate the motor power and head first, and then select the pump based on these two quantities, not the flow rate of the pump.

There is relevant software in the forum that can be used for calculations. Search first. If you can't find it, contact me.

1. Effective power - P effect = 9.8×Q Flow rate Q (m3/h) Lift H (m) Density ρ (kg/m3) η Pump efficiency

I am not doing design, but calculating the flow rate at the pump outlet based on the design.
