statistics to help my students with an ecology investigation

rmine size of piping for a water, wastewater, and stormwater system for an addition to a building on our campus. I am given maps of the existing conditions. I have calculated the new water demand which has to be used to determine the size of the pipes, though I am not completely sure if I did that right. I have a lot of information which I have compiled into a one drive file that I can share. I am able to help provide any information that is necessary since I am familiar with what the files contain. I have attached a document which explains everything that I need to do. I am able to use the existing network for the most part so routing of it should be easy. The part I am unsure about is determining the size of the pipes. For the water, I believe I can use mannings equation. For wastewater, I am unsure. For stormwater, I am to use the rational method and I have an excel tool which makes that easy for someone who knows what they are doing. Please help ASAP. I have to be done with this before tuesday afternoon. I am in central time zone(11:20pm right now).
