Figure Q1.1 below shows a diagram of a proposed sewer network. The pipe slope and proposed diameter is also shown. Use the attached HRS chart and the proportional discharge/ depth chart to complete the design table and calculate the maximum flows and velocities in the pipes. Also calculate the maximum capacity of the pipes. Provide a brief commentary on your results. Assume that each house generates 0.0116 litres per second during dry weather flow conditions.
