## The Calculator Encyclopedia Calculates the Hydraulic Mean Depth or Hydraulic Radius of Flow in Open Channels | Fluid Mechanics

Hydraulic mean depth or hydraulic radius can be defined as the cross-sectional area of flow divided by wetted perimeter.

Wetted perimeter is the perimeter of the cross sectional area that is “wet”.
Hydraulic mean depth or hydraulic radius is a very important parameter in flow in open channels and fluid mechanics calculations.

The formula for computing hydraulic mean depth or hydraulic radius is:

R = A / P

Where:
R = Hydraulic Depth
A = Cross-sectional Area of Flow
P =  Wetted Perimeter

For Example:

Find the hydraulic mean depth or hydraulic radius of flow in an open channel where the cross-sectional area is 150 m2 and the wetted perimeter is 100 m.

From the example we can see that the cross-sectional area is 150 m2 and the wetted perimeter is 100 m.

R = 150 / 100
R = 1.5

Therefore, the hydraulic mean depth or hydraulic radius is 1.5 m.
