2. For the drainage system as shown in figure below, determine the design flow and determine the pipe size for each of the sewer section by rational method. The rainfall intensity (in/hr) is given by the IDF curve in second figure. The design frequency storm is 10-year storm. Flow from each area is shown by an arrow. The flow velocity in each pipe can be calculated by Manning's equation or Hazen-William equation by assuming a full...
