It explains critical flow characteristics for flow past an irregular surface domain. Hydraulic mean radius is different from the hydraulic radius. This answer is correct. Chemical engineers don't have to deal with this, it is effectual in HYDRAULICS section of CIVIL engineering.

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.

@Harry.
Mean velocity is average velocity. For laminar flow, it is glf of the max velocity. Then coming to pressure, as pressure increases max velocity decreases so as average velocity also decreases.

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

Can anyone explain it in details that what is hydraulic mean depth and mean velocity. Please, I don't understand.

Hydraulic mean depth defined as the ratio of the area of flow section to the top surface of the fluid.

Not understanding, Because it is not defined between mean diameter, flow rate, velocity.

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