Use the following values for your calculations: width of channel, b = 36 cm; roughness, n = 0.01. 1. Tabulate your measurements: flowrate Qex, velocity Vex, and depth, h. 2. Calculate the flow area, A = bh, wetted perimeter, P = b + 2h, and hydraulic radius R = A/P for each flow measurement. 3. Estimate a theoretical flow rate using Manning's Equation: AR²/31/2 Qth 72 4. Estimate a flow rate using our velocity measurement, Q = VexA. 5. Calculate the percent error between your measured flowrate Qex and the value you estimated with Manning's equation Qth 6. Calculate the percent error between your measured flowrate Qex and the value you estimated with the Continuity equation Qu. 7. Explain the sources of your error in both Manning's equation and Continuity equation.
