How equivalent diameter related to the mean velocity?

Clearly explain what is mean velocity and when pressure increases velocity decreases but it is how related to mean velocity?

Please, someone explain it in detail.

Pressure and velocity of liquid depend upon the diameter of the pipe through which liquid flow.
If the diameter increase pressure will be high and velocity will decrease. In above case diameter is decrease so mean velocity will be high and pressure will also decrease.
If the diameter increase pressure will be high and velocity will decrease. In above case diameter is decrease so mean velocity will be high and pressure will also decrease.

The flow rate don't depend on diameter the change in velocity.

Hydraulic mean depth is flow area/wetted perimeter answer should be C.
