As Director of the Water District for Dawes County, Nebraska, you are responsible for all water projects within the County. The newest project that is scheduled to occur in your area of responsibility is the construction of a secondary reservoir with a design water surface elevation of 45 feet above the primary reservoir water surface elevation, currently located at the edge of the town of Chadron (elevation 4,233 feet). The connecting pipe will be 575 feet long with a 12" diameter and made of galvanized iron. There are to be two 90° elbows, each with an r/d of 6, located 100 and 225 feet downstream of the secondary reservoir, and one gate valve, normally wide open, 75 feet upstream of the primary reservoir. Water temperature averages 65° F. Your task includes the following: a) Determine the discharge that will occur between the two reservoirs. b) Draw both the HGL and the EGL for the system.
