Hydraulic efficiency of the pump is defined as the ratio of fluid Power to absorbed power. This efficiency is maximum only at one capacity value. It is lower in other capacities.
So the correct answer should be; increases and then decreases.
So the correct answer should be; increases and then decreases.

According to me, option D is correct because when we plot a curve between flow rate and efficiency shows same.

From Pump Characteristic Curve, With an increasing flow rate, the hydraulic efficiency of a centrifugal pump first increase to the peak efficient point and then decreases.
The correct answer is option D.
The correct answer is option D.

Monotonic means there is no constant value. When the efficiency starts falling it falls sharply or continuosly in this case.

As per centrifugal pump performance curve efficiency first increase with flow rate and after reaching the best efficiency point efficiency goes on decreasing, because any equipments, instruments and electrical designed and fabricated for maximum calibration value after that efficiency decreases.

Hydraulic efficiency = Total head/ideal head.
So I think it should remain same.
