3.1 Base flow

The quantities of water required to supply a plant are determined by :

• the number of users, which gives the daily consumption ;

• the number and capacity of devices used to determine cross-sectional area and flow rate.

Each type of device is characterized by its drawing capacity, known as the basic flow rate, generally measured in liters per second (L/s) and sometimes in cubic meters per hour (m ^3...
