The table above shows a typical $($average$)$ diurnal water demand pattern at a high rise residential building in an urban estate. The estate comprises $10$ such high rise residential buildings.

$($a$)$ Calculate the urban estate Average Day Demand $($ADD$)$ in litres per day $[6$ marks$]$

$($a$)$ Calculate the urban estate Maximum Day Demand $($MDD$),$ the Maximum Hour Demand $($MHD$)$ and Maximum Monthly Demand using the Goodrich formula:

$={180\mathrm{.}1}^{-110},180*t^{-0\mathrm{.}10}$
