Assignment Prompt & Instructions
WATER FILTRATION PLANT
A fresh young graduate from Bahrain polytechnic came up with an idea to set up a Water Treatment Plant to purify polluted ground water. Figure 1 shows the schematic of the water filtration plant with two overhead tanks namely overhead tank 1 and overhead tank 2. The plant also has 3 filtration units namely filtration plant 1, plant 2 & plant 3 respectively. The idea is to purify impure ground water and store it in overhead plant 2.
Limitations –
1. You cannot change the direction of flow.
2. You cannot increase the number of pipes. Each arrow is a pipe in Figure 1.
3. You cannot change the heads.
Your design should mainly consist of various activities that include pressure drop calculations, selection of pumps, design of venturi meter and selection of check valve, the details of which are shown below:
A. You are to size the pipelines and to select a suitable pump. The proposed piping layout is as per the attached schematic. You are given details of the required lengths of pipes and the number of bends involved to get the chilled water to each of the cooling coils. There are isolating valves around each piece of equipment so that maintenance work can be carried out. (LOs: 1,2,3,4)
B. You have also been asked to design a venturi flow meter, a form of flow measurement device, to be installed after the pump so that the total water flow can be measured on a continuous basis. You will need to demonstrate how the venturi will work. (LOs: 2,3)
C. Select the appropriate check valves which must be fitted before each coil at the supply lines according to all the engineering parameters of the system. (LOs:2,4,5)
D. Prepare a PowerPoint presentation file outlining your system design, including pipe and fittings sizing, pump and motor selection, design of the venturi and selection of the check valves. (LOs: 1,2,3,4,5)
