Even then, a vast population of the world is without safe piped water facilities. 6 Full PDFs can scour the pipe material and damage the force main. An equivalent pipe is an imaginary pipe in which the head loss and discharge are equivalent to the head loss and discharge for the real pipe system. 7 hoursfor sanitary systems in building. This is equilavent to using average daily flow (design flow) with the pipe flowing approximately 40% full. For a given pipe size, fluid properties and flow rate, the hydraulic analysis should provide the pressure and temperature profiles along the pipeline for steady state and transient conditions. Dead legs are defined as any dead -ended section of pipe more than 4 pipe diameters long that occurs when a valve is closed. By Dr. Ali Hammoud Associate professor in fluid mechanics & hydraulic machines 604.1; CABO- 1995, Sect 3403.4) (piping) design criteria may be relaxed to some degree.
