Abstract
This paper continues from where the first part of the paper ended and examines the transform mechanism of building pulmbing systems. The transform coefficients are defined so the transform mechanism can be handled quantitatively. For quantitative conversion, the coefficients for sanitary fixtures and standard drainage piping are calculated from the results of analysis of the experiments and data shown in the first part of the paper. The peak drainage flow rates are estimated from the peak water supply flow rates of the sanitary fixtures by using these transform coefficients. The authors verify these coefficients by estimating the peak drainage flow rates of the model piping and show that they are the proper coefficients. An example in which water usage accummulation by time frame is considered is given for a residence of an appartment house. The authors show that the peak drainage flow rates can be estimated by peak water supply flow rates multiplied transform coefficient as described above.
