Option 2 : Power decrease with speed

Concept:

The performance characteristic curve shows the variation of different parameters (discharge, power, and head) with speed and discharge.

Below are the characteristic curves for centrifugal pumps:

Clearly, power increased with discharge and speed

Manometric head slightly increased then decreased with discharge

Efficiency also have a curvy relationship with discharge.
