WebUpfeed and downfeed distribution system – water pressure from the water supply main is relied on to drive water flow through the system. Water pressure in building water supply mains typically ranges from 40 to 80 psi (275 to 550 kPa), with 80 psi (550 kPa) considered the upper limit for most systems plumbed with metal pipe and 40 psi the ... Webdiameter of downfeed pipes. Then, the traditional method of pipeline design is used to determine the diameters of downfeed pipe in different floors of the building. First the flow rates were estimated then the energy head loss in downfeed pipes as well as branch pipes were computed by both Darcy-Weisbach and Hazen William’s equations.
