Data Sheet Slope: 0.1% Channel width: 36 cm Roughness: 0.01 Measured Flowrate e Flow Depth Comments ex Measured Velocity V [m/s] [h] [m3/hr 50 0.76 6.1 cm 60 0.8 7.0 cm 70 0.85 7.8 cm 80 0.90 8.5 cm
Use the following values for your calculations: width of channel, b = 36 cm; roughness, n=0.01. 1. Tabulate your measurements: flowrate Q velocity V , and depth, h. ex 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: AR SP 0 Qth = n 4. Estimate a flow rate using our velocity measurement, Q, EVA. 5. Calculate the percent error between your measured flowrate Qex and the value you estimated with Manning's equation Q, th 6. Calculate the percent error between your measured flowrate Q and the value you estimated with the Continuity equation Q ex 7. Explain the sources of your error in both Manning's equation and Continuity equation
