Question 2 Storm sewer system is to be provided to drain storm water to protect urban areas from flooding after episodes of rainfall. Storm sewer layout along with the contributing areas drained in specific sewer lines is shown in Figure Q2. Design the storm sewer system for "gravity flow" using the data given in Table Q2 assuming that the entry time to the pipe is the same for all sections and is equal to 6 min. All pipes are circular and made of concrete. All areas are in hectares.
