Hydraulic Conditions in Foul Water Stacks

Foul water stacks are a separate chapter in the design of sanitary installations, especially high-rise buildings. The problematic part is complicated hydraulic conditions stacks, which lead to high values negative pressure and overpressure. Exceeding maximum leads extraction from traps, causes spread annoying smells interior. Another jumps caused by sudden change velocity stack, above direction stacks. Such changes cause excessive vibrations noise that building structures surrounding areas. contribution deals with issue flow foul assessment overpressure, technical solutions ensure optimal drainage systems Based on measurements were performed companies abroad, authors prepared graphs fluctuations for selected boundary conditions.
