This research first examines the current condition
of the building drainage system design in Taiwan,
including an investigation 51 apartment buildings.
The second part is to experiment on the air pressure
in the vertical stack drainage system . An
experimental device that simulates a medium-height
apartment was set up to provide empirical parameters
and model verification at NTUST. A considerable
progress has been made in predicting the air
pressure distribution within vertical drainage
stacks.
The third part focuses on a 2-pipe vertical drainage
stack for conducting the empirical...
