The City of Johannesburg has contracted Aveng Infraset company, which is involved in the design and manufacturing of high quality engineered precast concrete stormwater drains. The drain is intended to be used in one of the civil engineering special projects. The dimensions of the drain are W (mm) by D (mm), where D and W are depth and width respectively. The design team of engineering technologists at Aveng conducted computer simulations for the water infrastructure (drain) design and noticed a hydraulic jump formation. The ratio between upstream depth and downstream depth of the hydraulic jump is 1/3. The recurrence interval for the drain in flooding conditions is 1 in 10 years to accommodate the flow causing the hydraulic jump. Consider the ratio between width and depth to be 2.587. If the upstream velocity is 10 m/s, determine the following: 3.1. Type of flow regime upstream and downstream of the jump. (Substantiate your answer). 3.2. The discharge (in m®/s) 3.3. Energy (in m) dissipated through the hydraulic jump. (Scale 1-5 for 10 points per indicator: 40 points for 4 indicators, OR 10 point on average per question)
