SECTION A (P3.1, P3.2, P4.1, P4.2)

Introduction

You have been selected to participate in the

Annual Design Competition conducted by

the Faculty of Technology & Built

Environment of the Liverpool John Moores

University (LJMU), UK.

Liverpool John Moores University is a

thriving, vibrant university located at the heart

of Liverpool. Their three large campuses

ensure that no matter where you go in

Liverpool, you are never far away from an

LJMU building.

It is also a member of theEuropean University

Association and the North West Universities

Association. At present, LJMU serves more

than 24,000 students comprising 20,410

undergraduate students and 4,270 postgraduate

students, making it the largest university in

Liverpool by student population as well as

the twentieth largest in the United Kingdom.

New advances in digital technology and

science have placed LJMU at the forefront of

exciting developments in areas such as

multimedia, sports science and space

exploration.

The University is organised into five Faculties

spanning Arts, Professional and Social

Studies; Education, Community and Leisure;

Health and Applied Social Sciences; Science;

Technology and Environment.

The Design Competition is a major event

that is held every year by the Faculty of

Technology and Environment. This Year

LJMU has planned to get the participation

from the partner institutes from all around

the World.

This time the Design competition comprises several categories. And you are selected to participate in

the Fluid & Hydraulic System Design Category. The Design Project details are given below.

Design ProjectWater Distribution System

You have to select an area in Sri Lanka and should come up with a Detailed Design of a Water

System that will be useful for Sri Lankans. That can be any water design which utilizes the knowledge

of design of Pipe mains, Open Channels and Pump selections.

Main Design: You can choose any design scenario such as a pure water distribution system, well

water pumping system, channel diversion system, etc. The selection of the locations, choosing the

appropriate route will also be a part of your design project. But make sure that this system should help

to improve the living standard of the particular area.

Main features of the Water Distribution System.

Distance: >2 km Elevation Difference: > 20 m Design of a Pump main to connect two reservoirs (Tanks) including Pipe line design

and pump selection

Design of an Open channel Providing a Layout of the Water Distribution System.

Also the detailed designs should include:

Analysis and solving of practical pipeline flow problems and determining headloss/discharge/pipe size as required using a variety of methods including current computer

software methods (P 3.1)

Design channels to convey known discharges with specified design criteria, eg. velocity offlow using a variety of methods including current computer software methods (P3.2)

Select appropriate pump characteristics to suit a given hydraulic situation by selectingappropriate pump/s, using manufacturers published pump characteristics curves (P 4.2)

Prepare diagrams showing hydraulic structures, pipe fittings and measuring instruments forpractical civil engineering application eg. pumping station (P 4.1)

Guidelines for Cost Effective Design of Pipelines

The design velocity should not be less than 0.6m /s in order to avoid depositions andconsequent loss of carrying capacity.

The design velocity should not be higher than a maximum value according to the diameter ofthe pipe, in order to avoid scouring of the pipe material. Table 01 provides the data for

maximum allowable values of different pipe sizes of Steel.

The water distribution will be done only from 11.00 pm to 5.00 am (6 hours/day), consideringthe optimum use of electricity.

Chosen pipe material is Steel. Use table (01) to get the maximum allowable values ofdifferent pipe sizes of steel.

DESIGN PROJECT: PART A

DESIGN THE PUMP MAIN BETWEEN AQUINAS BUILDING & JOHN FOSTER

BUILDING, USING PROVIDED DATA AND THE DESIGN INFORMATION.

To Support with your Design you may use below step by step procedure.

a. Find the flow through pipe line in cubic meters per second considering the given requirementand criteria.

b. Using above given data, find the suitable diameter for the pipe line, considering the calculatedFlow rate and minimum & maximum allowable velocities.

c. Find the Major Head loss along the pipe line.d. Find the Minor Head loss along the pipe line.e. Apply the Energy equation for the Full Pump Main system. State any assumptions made.f. Find the Energy head required from the Pump.g. The figure 08 includes performance curves of three different centrifugal pumps given to you.

Select the most suitable pump giving justifications for the selection.

h. Provide a Design report including all the finalized design information with a proper layout forthe Pump main.

(The report must include all finalized design values, diagrams to illustrate the design, Water

pumping arrangement other necessary fittings for the pipe line using proper symbols for the

components (eg: Pump, gate valves, tanks, etc. See Annex 01)

Figure 05: Performance Curves of Three Different Centrifugal Pumps

*BEP- Best Efficiency Point

To support with your calculations use below given illustration.

Figure 06: Head of the Pump against Capacity (Flow)

Plotted is the head of the pump against its capacity (Flow). The head of a pump is read in feet or

meters. The capacity units will be either gallons per minute, liters per minute or cubic meters per

hour. You have to consider the Flow and the BEP, which gives the required head for your system.

Ideally a pump would run at its best efficiency point all of the time, but we seldom hit ideal

conditions. As you move away from the (Best efficiency Point) BEP the shaft will deflect and the

pump will experience some vibration. You'll have to check to see how far you can safely deviate from

the BEP and still get satisfactory operation (a maximum of 10% either side is typical).
