Find the flow in a 15m wide rectangular channel for which the critical depth is 3m. | 244.12 cu.m./s. 162.7 cu.m./s. 220.8 cu.m./s. O 140.8 cu.m./s.

Problem 7-61

For #5-7, assume there is a creek with a width of 4.6 m, depth of 23 cm, slope of 0.001 m/m, and discharge of 0.13 m³/s. 5. Assuming a rectangular cross section, what is the hydraulic radius of the creek to the nearest cm? 6. What is the average flow velocity to the nearest cm/s? 7. And what is the channel's Manning's roughness coefficient (using SI units) to the nearest hundredth?

Answer as fast as possible, use 3 decimal
