Question

The figure below shows a sewerage system with $4$ manholes. Eash pled has a length of $150m$

and ropographical elevation information is given in brackes. Manhole $2$ receives $10\frac{u}{s}$ of

Extra industrial wastewater In Marihoie $3,$ the imer depth is $27m$ Design the $3.$pipasystem

via the Excel table approach. Thie parmeters related to the system are isted below:

Population Density $=2$

$Gh=0\mathrm{.}01(\frac{L}{s}\frac{?}{m})$

$n=0\mathrm{.}015$

$V_{\text{r}\text{a}\text{i}\text{k}}=0\mathrm{.}5\frac{m}{s}$

$V_{\text{l}\text{a}\text{x}}=2\mathrm{.}5\frac{m}{s}$

$\{\begin{array}{c}\text{:}[\frac{h}{d}{]}_{\text{i}\text{o}\text{m}}=0\mathrm{.}1\end{array}$

$(h)\frac{?}{?}d$
