CIVL $215$ Design Project $2023$: Instructions

You are the Chief Engineer for a prominent hydraulic engineering consultancy. Your

client wants to pay you lots of money to design a system to deliver $1$m$^(3)//$s from

reservoir A$($z$\_($A$)=0\mathrm{.}3($km$))$ to reservoir B$($z$\_($B$)=0\mathrm{.}5($km$)).$ Between the two

reservoirs the variation in elevation is given by:

z$^(**)=$a$+$bx$^(**)+$cx$^(**2)$

where z$^(**)=$z$//$Delta z with Delta z$=0\mathrm{.}2$km; and x$^(**)=$x$//$L$,$ where x is the horizontal

distance from A $,$ and L is the horizontal distance $($in km $)$ from A and B $($where L is

equal to the first three digits of your student number$).$ The maximum pipe elevation

occurs at x$^(**)=0\mathrm{.}6.$

The system is to consist of commercial steel piping with a roughness epsi$=0\mathrm{.}2$mm

and a pressure rating of $200$ m head. The total cost of purchasing pipe and

constructing a pipeline is listed below for various pipe sizes. Pumps that can deliver

$1$m$^(3)//$s at $100$ m head cost $$15,000,000$ each $($installed$).$

Note $1$: Theoretically, a pipeline may be designed to allow pressure to fall to the

vapor pressure. In practice, however, water usually contains dissolved gases that

will vaporize well before the vapor pressure point is reached. Such gasses dissolve

very slowly. They can move with the water in the form of large bubbles that disrupt

the flow. Therefore, the minimum absolute pressure should be $30$ kPa $-$ use this

figure in your design calculations. Assume the absolute atmospheric pressure is $100$

kPa $.$

Note $2$: The pressure rating of a pipe is the maximum pressure that it can withstand.

Note $3$: You can bury the pipe for $$10,000//$km per meter of depth.

CIVL $215$ Design Project $2024$: Deliverables and Dates

This project is to be completed in phases to ensure that you stay $"$on$-$track".

Pipeline Geometry $(2$ marks$).$ Show that for engineering purposes the length of

your pipeline is equal to the horizontal distance between A and B$.$ Find the values

of a$,$b and c$,$ as per the basic instructions. Due $11$:$59$ pm Friday October $18*.$

Standard Solution $(6$ marks$).$ The simplest, or standard, solution to this project

involves calculating the cost of the pipeline for each of the different pipe

diameters. Choose the diameter that gives the lowest total cost $($i$.$e$.$ the cost of

the pipeline plus the cost of the pumping stations$).$ Plot the pipeline, and the EGL

and HGL for the lowest cost solution. The calculations and plot can be completed

using any technique you like. The calculations can be conveniently performed

using a spreadsheet. You should include a Table, a Figure and some relevant

explanatory text. You should be able to present your answer on one $($ideally$)$ or

two pages. Due $11$:$59$ pm Friday November $8^("$th $").$

Final Design $(12$ marks$).$ Improve on your standard solution. Try to come up

with money saving modifications to your design. Present your final design in a

technical report. Due $11$:$59$ pm Friday December $6^("$th $").$

Bonus marks will be given for the most innovative, money saving solutions.

PLEASE PART $1,2$ and $3$ FOR L$=601$KM$.$
