5. A storm sewer pipe has a diameter of 30 cm and is constructed on a slope of 0.0045 m/m. A. (6 pts) What is the flowing full quantity (le, flow rate) and velocity of flow for a roughness coefficient of n = 0.013? B. (3 pts) How much will your answer to part A change if n = 0.0117 C. (5 pts) For a roughness of 0.013, what is the flow rate and velocity when water is at a depth of flow equal to 18 cm? D. (5 pts) What depth and quantity of flow will be observed in the pipe when the velocity is equal to 0.55 m/s? 4. The following are data from a chlorine demand test on filtered effluent water: Sample number 1 2 3 4 5 6 7. Chlorine dosage (mg/L) Residual chlorine (mg/L.) after 10 min contact 0.20 0.19 0.40 0.36 0.60 0.50 0.80 0.48 1.00 0.20 1.20 0.40 1.40 0.60 1.60 0.80 A. (4 pts) Use Excel to plot the chlorine demand curve (for example see Figure 7-17). B. (2 pts) What is the breakpoint dosage? C. (2 pts) What is the chlorine demand at a dosage of 1.4 mg/L? 5.
