- 10. How would you determine the gap flow (i.e. major drainage system design flow) for an ARI = 100 years, taking into consideration that the minor drainage system which was designed for an ARI= 5 years is fully operational (i.e. unblocked-blockage is never an issue).The sewage from an area of 160 hectares is to be carried by a circular sewer (n = 0.013). Thepopulation density is 20 persons per hectare. Find the peak flow and minimum flow (40% of average flow)for an average sewage flow of 450 Lpcd. Determine the pipe size and slope to handle these flowsEstimate the maximum and minimum design wastewater flow rates from a 65 ha residential development that when fully developed will consist of 10% large lots (6 persons/ha), 75% small single- family lots (75 persons/ha), and 15% small two-family lots (125 persons/ha). The average wastewater flow rate when the sewers are first installed is expected to be 30% of the average wastewater flow rate when the area is fully developed. Assume an average per-capita flow rate of 350 (L/d/person). Neglect I/I.
- The sewage from an area of 400 acres is to be carried by a circular sewer at a velocity not less than 2.5 fps. Manning’s n = 0.013. The population density is 16 persons per acre. Find the maximum hourly and minimum hourly flows. Determine the pipe size required to handle these flows and the required slope. Assume typical per capita sewage quantities and typical peak factors for the determination of maximum and minimum hourly sewage flows. Allow a maximum velocity of 10 ft/sec and allow the pipe to flow full under maximum hourly flow conditions.Runoff data have been collected for a 4-hour storm over a 120 acre watershed as indicated in the table. If the total volume of water infiltrated during the storm was 3.0 Ac-ft and the Phi Index is 0.1 in/hr, sketch the rainfall hyetograph with EVERYTHING labeled appropriately. Also, report the depth and volume of precipitation (in inches and Ac-ft, respectively) for each 1-hour period.If a detention basin has a volume of 5 acre-ft, what is the required outflow from the detention basin in ft3/s if the required resident time is 8 hours? Q Answer = 7.6 cfs
- Determine the characteristics of a unit composed of 2 desilting channels treating a peak wastewater flow of 1500 L7s. A surface load of 40 m/h is assumed. The effective head or depth "P" is set at 1.5 m. Calculate: 1. Area of each channel 2. 2. Effective volume of each desanding channel 3. HRT 4. Cross-sectional area of each desanding channel 5. 5. Width of each channel.PROBLEM #3 ONLY!!! Problem 1: A storm drain system is shown in Figure P16.11. For the flow conditions indicated, determine the time of concentration from Point A to Point C using the Kirpich, Kerby, Bransby-Williams, and Federal Aviation Administration Methods. Problem 2: Using the Kirpich time of concentration you calculated in Problem 1 and assuming the watershed is located in Seattle, WA, determine the intensity for the 50-year storm. Problem 3: For the watershed in Problems 1 and 2, determine the peak flowrate(in ft3/s )for the 50-year storm event at Point Cusing the Rational Method.WATER RESOURCES ENGINEERING: The ordinates a one-hour intervals of a unit hydrograph are 350.2, 753.2, 1556.0, 1980.1, and 224.3 cfs/in. Determine the direct runoff hydrograph from a three-hour storm in which 0.6 inches of rainfall excess occurred in the first hour, 1.3 inches in the second hour, and 0.3 inches in the third hour. What is the watershed area in mi2?
- A proposed residential subdivision has an area of 260 ha and an average housing density of 15 dwellings/ha. The required fire-fighting flow rate is 4 US gallons per minute. Assume that on average 4.5 persons occupy each house and that the average daily demand is 385 Lpcd, determine (i) maximum daily and maximum hourly demands (assume peak factors of 1.5 and 5.0 for max. daily and max. hourly, respectively); (ii) the recommended design flow for the main pipe supplying water to the subdivision. Express all the flow rates in m3/minute.Determine the following:What is Rainfall-Run off Relation?Definition of HydrographWhat is a Hydrograph Separation?What is a Unit Hydrograph?Estimation of Discharge using HydrographWhat is Rational Formula and SCS Curve?Please type it in here instead of writing it on a piece of paperWhat is the maximum population that can be served by an 8-in. sanitary sewer laid at minimum grade using a design flow of 400 gpcd (gallon per capita per day) and a flowing-full velocity of 2.0 ft/sec? (b) Compute the diameter of a storm drain to serve the same population based on population density = 30 persons per acre, coefficient of runoff = 0.40, 10-year rainfall frequency curve, a duration (time of concentration) = 20 min, and a velocity of flow = 5.0 ft/sec.
