Principles of model choosen:

To make sure user can use normal water at the extreme pressure port

Daily average water consumption: Q=n*q*k/24000(m3/h) 

n---number of users

q---water consumption standard (L/n*day)

k---hour viriation coefficient

Water supply pressure: H=H1+H2+H3

H1: the vertical height difference from water pool lowest level to pipe network extreme pressure port

H2: the pipeline loss from pump discharge to pipe network extreme pressure

H3: using water equipment required pressure
