Calculation elements for feeder pipes
Designing water systems and installations - Fluid mechanics approach

It's worth remembering that the concept of feeder pipes has, for the sake of simplicity, been reserved for indoor networks.

In the case of water distribution to a building or establishment, and depending on the operating characteristics, the pipes are determined according to the following steps:

• determining needs,

• definition of basic flow rates,

• instantaneous flow calculation,

• calculation of simultaneity coefficients,

• calculation of probable flows,

• determination of diameters according to pressure drop and speed,
