| With the elevation of people's living stantard , the improvement of the condition of inhabitation and the change in the quantity of water daily used by every man, the rule of using water in life inside the dwelling house is also verifying .But the formula of calculating the flux designed for water supply inside the buildings is still following the traditional one which has been educed from square root.It only reflects the effect of the number of sanitary sware on flux designed but not the effect of the frequency of using water. So,when we use it to devise projections,we may find that the numerical value designed is ofen bigger than the actual .which has resulted in that the hydraulic pressure provided by the system is high enough to waste energy sources .In allusion to these problems, the author investigates and surveyes the data about the quantity of water used,abandoned the former method of deducing the formula and calculated an expressions in pointIn order to gain the formula , this text wields binomial distributing and linearity regression to analyse and dispose the abundant data and then gain the formula which has been compared with what is deduced from square root on the basis of the actual data and then demonstrate the applicability of the formula... |
