Question

The hydraulic mean radius of a circular sewer of diameter \(D\) is given by

• A. \(\dfrac{D}{4}\)
• B. \(\dfrac{D}{2}\)
• C. \(\dfrac{D}{3}\)
• D. \(\dfrac{D}{6}\)

Hint:

Hydraulic mean radius: \[ \boxed{ R=\frac{A}{P} } \] For a full circular pipe, \[ \boxed{ R=\frac{D}{4}. } \]

Answer 1

The Correct Option is A
