Question: Problem: An earth channel is trapezoidal in cross - section with a bottom width of 1 . 8 m and side slopes of 1 vertical

Problem: An earth channel is trapezoidal in cross-section with a bottom
width of 1.8 m and side slopes of 1 vertical to 2 horizontal. Taking the
friction coefficient in the Bazin formula as 1.3 and the slope of the bed as
0.57 m per kilometre, find the discharge in cubic metres per second when
the depth of flow is 1.5 m .
