Which of the following statements about Energy Grade Line (EGL) and Hydraulic Grade Line (HGL) is incorrect? When the diameter of a pipe decrease, the slope of EGL will decrease (become flatter). O EGL is an indicator of total head throughout the pipeline system. O Valves are devices that may cause a sudden drop in the EGL and HGL. O Unless a pump is added to the pipeline, HGL decreases in the direction of the flow.

Sketch a typical Streeter-Phelps oxygen-sag curve and state the limitations of the Streeter-Phelps equation shown below: k, Lo -kt D= k2 – k -e (b) Wastewater discharges through an outfall into a slow moving river that has a mean velocity of 3 cm/s. After initial mixing, the dissolved oxygen concentration in the river is 9.5 mg/L, and the temperature is 20°C. The ultimate BOD of the mixed river water is 30 mg/L, the rate constant for BOD at 20°C is 0.48 di and the re-aeration constant at the same temperature is 0.72 d.
