2. What is the flowrate (cfs) for a 5 foot wide (length) rectangular weir with an invert of 1.0 feet if the water surface is at elevation 5.0feet? (a) <

50 cfs (b) 50-80 cfs (c) 80-100 cfs (d) > 100 cfs \text { Rectangular Weir }-\mathrm{Q}(\mathrm{cfs})=\mathrm{C}^{\star} \mathrm{L}^{*} \mathrm{H}^{\wedge} 1.5 C = 3 L (ft) is the weir length/width H (ft) is the height of the water above the weir invert
