|Answer should be 1.
Because head loss per unit length does not depend on the depth of water in a sewer pipe.

|(.81/.5) = 1.61.
Flowing full in pipe = 81%.
Flowing half in pipe= 50%.

|You are right, I agree @Shubham.|
|Roy said: (Nov 26, 2017)|
|1 is the correct answer.|

|Head loss due to friction/unit length of pipe is proportional to mean velocity square V^2 and inversely proportional to diameter D of the pipe.
V = volumetric flow rate remains same.
So, head loss due to friction: ratio when flowing full/when flowing half full = 1.

|Head Loss per unit length is independent of sewer running in full or half full condition.|
