Now you have determined the stormwater flow for the area according to the rational method. Youhave a flow in each of the pipe segments, so now you have to check if the pipe can handle that amount of flow and that comes down on the hydraulic design which is explained in this lecture. Some attention points are:

• Can a pipe handle the amount of flow
• Pressurized and part-full pipe flow
• Local losses
• Quick recap of fluid dynamics
