A Flow Discharge Of 35 M S Is Measured In A Rectangular Concrete Channel 4 M Wide With A Flow Depth Of 3 1 M Given The 1 (415.17 KiB) Viewed 63 times
A flow discharge of 35 m®/s is measured in a rectangular concrete channel 4 m wide with a flow depth of 3.1 m. Given the channel bed slope is 1 i. Determine the Manning's roughness coefficient for the channel. ii. It is decided to replace the above channel with a trapezoidal channel with 45° side slopes. The concrete finish will be the same. Calculate the profile of the most economic section for the above discharge rate given the following equation: b+2zy = 2y71+z2
