2. Determine the (a) actual discharge, (b) theoretical discharge and (c) weir coefficient over a 90° V-notch weir for a head of 180 mm flowing 400 liters in 20 seconds. 3. In a river 60ft wide, having an average depth of 3.4ft and a mean velocity of 1.15 fps, a contracted rectangular weir 30ft long is to be constructed. Determine the head over the weir, assuming free fall. 4. A sharp-crested weir 4ft high extends across a rectangular channel 10ft wide. If the measure head is 1.22ft, determine the discharge using the Francis formula. N
