Use group $10$ data A$.$ Instructions

This design project should be completed by groups. Each group is formed by $36$ students.

Each group should submit a project report and the spreadsheet calculations in Excel format. Full details of the design calculations method and analysis should be presented in the report in a logical manner.

Individual contribution to the reported should be clarified in the report.

Commercial simulation software cannot be used in the design.

Design Data

Each group is required to design the water supply pipe networks. The pipe network covers all major $11$ buildings $($Block A to K$)$ within the site. Different group is assigned with different building information.

Fire water demand is not considered in this case and topography of the site is virtually

flat. The working pressure at the inlet point of the pipe network is assumed to be $65m$

Darcy Weisbach equation should be used in the design calculation.

Allowable velocity range in pipes: $0\mathrm{.}5$ to $2\mathrm{.}0\frac{m}{s}$

Working pressure in pipes:

Standard pipe sizes $($pipe diameters

$20mm,30mm,50mm,100mm,150mm,200mm250mm,300mm,350mm,400mm450mm,500mm,600mm,750mm,900mm,1050mm,1200mm,1350mm,1500mm$ and $600mm$

C$.$ Water Supply and Water Demand

The project group is required to estimate

Population in each building

Design flinty rate of water demand in the system

flow $=$ maximum daily rate $=1\mathrm{.}5$ average daily rate

D$.$ Pipe Network Design and Pump Selectio

Hardy$-$Cross method should be used to perform the following assessments:

$.$ Determine the sizes of pipes in the system by satisfying the required demands at various

locations and the allowable working pressures in pipes. Minor losses in the system can b

ignored in this case.

The error $($correction factor$)$ in the final trial should be less than $10$

$3.$ Record the pipe diameter, velocity, flow rate and head loss in each pipe and the pressure at

each node.

$4.$ Determine whether pumps are required for the system. $($Hint: The minimum requiremen

for the normal operation of taps in a flat is $\frac{0\mathrm{.}5}{b}ar.$

If pump is added for a certain building. Select proper pump in the market and provide its

detail specifications.

$6.$ Present details of the calculations and clearly describe the design steps.

Note: The system should be adequate to meet the design demands. Ideally, the pipe sizes of the

system should be such that they cannot be reduced further without violating the pressure and

E$.$ Report Requireme

Each group is required to submit a project design report covering the pipe network design

and calculation process. The design report should cover the contents as listed in the table
