The pipe network analysis lab is a computational lab designed to familiarize students with the analysis of common pipe network problems, such as networks for water distribution sys- tems. Water distribution systems (WDSs) are complex, critical infrastructure systems that transport water over vast distances from sources to consumers and can contain thousands of components. There are over 150,000 such systems in the United States alone, servicing more than 80% of the public. The simplest WDSs contain sources of water (such as reser- voirs), consumers, and pipes to convey water from the sources to the consumers by gravity. The pressure heads and flow rates of such gravity-fed systems can be estimated by solving the mass balance and energy conservation equations, provided that consumer demands and pipe characteristics are known. However, most WDSs include additional control elements to ensure that all demands and pressures are met, e.g., tanks allow for water storage in times of low demand or high supply, pumps add pressure head, and valves can limit pressure head and flow
