A reservoir with a constant water level that is 200 m is supplying Q m³/s water to a downstream village that is 10 km away. The value of the variable Q can be determined by the formula in Table Q3. Variable Q Table Q3. Variables to be used in Question 3 Formula V₂+0.1V₁+1.5 Value (a) Design an outlet weir (width or opening angle, and crest height) and calculate the water depth above the weir to ensure a constant flow rate leaving the reservoir, if the weir is: (i) an Ogee weir. (C=1.85) (ii) a rectangular board-crested weir. (Cd=0.62) (iii) a triangular thin plate weir. (Cd=0.59) A reservoir with a constant water level that is 200 m is supplying Q m³/s water to a downstream village that is 10 km away.
