1. The pressure downstream from a tank is determined by the tank, not by the upstream pressure. The source is connected to pipe1, pipe1 is connected to valve1 and so on. A source supplies water to the system. Tanks decouple back pressure as they do pressure and flow. This is the amount of water passing through the component per unit time. It models a liquid distribution system, consisting of pipes, valves, tanks and other components. The Tick() method in switch uses the address of it owner tank to directly access the tank contents. Back pressure goes the opposite way from flow and pressure. The integrity of the systems are broken down into physical, hydraulic, and water quality.[3]. Sometimes the flow, pressure or back pressure are the same on both ends of a component. Of course Console.WriteLine() provides a very unsophisticated output system.

A radial system delivers water into multiple zones. Long term exposure to copper may cause liver and kidney damage. Biofilms are usually formed near the end of the distribution where the water circulation is low. They can also be temporarily used to serve fire fighting demands during a power outage. Water quality can be deteriorated by the internal corrosion of piping in distribution systems. This reduces the friction loss when water is transported over a water main. These values are all stored in objects of the Component class. Contact Us to ask a question, provide feedback, or report a problem. [9], Storage facilities, or distribution reservoirs, provide clean drinking water storage to ensure the system has enough water to service in fluctuating demands (service reservoirs), or to equalize the operating pressure (balancing reservoirs). Corrosion of iron materials causes the discoloring of the water that is shown as rust-coloured water or red water. In this application it's easy to see what the classes should represent. A standpipe is slightly different from an elevated water tower in that the standpipe allows water storage from the ground level to the top of the tank. • Recirculation pumps: used within a treatment plant. The bottom-line characteristic of components in the water system is flow. If using a windows application we may display a graphic output showing the pictures of each component. • High-service pumps: used to discharge water under pressure to the distribution system • Booster pumps: used to increase pressure in the distribution system. This includes the corrosion of metal pipe surfaces and connections. This is due to the digital nature of the simulation. Structural deterioration may be caused by many reasons. A water distribution system consists of pipelines, storage facilities, pumps, and other accessories. Water is taken from a feed hydrant into a temporary pipe. Being at the central location reduces the length of the water mains to the services locations. [5] World Health Organization (WHO) uses the term water transmission system for a network of pipes, generally in tree-like structure that is used to convey water from water treatment plants to service reservoirs, and uses the term water distribution system for a network of pipes that generally has a loop structure to supply water from the service reservoirs and balancing reservoirs to water consumers. It's transmitted from the downstream component to the upstream component. (when the tank is almost empty). Besides flow both pressure and back pressure must be connected since they are also transmitted from component to component. In opposite to pressure is back pressure. During the hydrant flushing, consumers may notice rust color in their water as the iron and mineral deposits are stirred up in the process.
