Question
Download Solution PDFCalculate the mean hydraulic radius of an open channel whose cross -sectional area is 30 m2 and wetted perimeter is 80 m.
Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFExplanation:
Hydraulic Radius \(= \frac{{{\rm{C}}/{\rm{S\;area}}}}{{{\rm{Wetted\;perimeter}}}} = \frac{{\rm{A}}}{{\rm{P}}} = {\rm{R}}\)
Hydraulic depth \(= \frac{{{\rm{C}}/{\rm{S\;area}}}}{{{\rm{Top\;width}}}} = \frac{{\rm{A}}}{{\rm{T}}}\)
Given:
A = 30 m2, P = 80 m
Calculation:
\({\rm{R}} = \frac{{\rm{A}}}{{\rm{P }}} = \frac{30}{80} = 0.375\)
