Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFSection factor:
- Section factor (Z) for critical flow computation: It is the product of the wetted area and the square root of the hydraulic depth, D
Z = A × √ D
40 = A × √4
A = 20 m2
Hydraulic depth (D) = A/T
Where A is the area of cross-section and T is the top width of the channel
4 = 20/T
T = 5 m
Additional Information Section factor: Section factor, Z, for uniform flow computation: It is the product of the wetted area and the hydraulic radius raised to the two-thirds power.
Z = A × R2/3
