Their value, that essentially depends from the type of use and from the sommatoria of the nominal courses, can be determined with the charts 2, 3, 4, or with the following formula derived by the DIN 1986: PF = F · (CF) where: CF= FLOW of project l/s, F = Factor of contemporaneity that you/he/she can normally be considered equal to: –0,5 for residential buildings and offices; –0,7 for schools, hospitals, restaurants, community and similar; –1,2 for industries and laboratories. PF = PEAK FLOW (sum of the nominal courses that you/they unload in the trunk of net considered), l/s
