Chronology: N….200.. to J… 20.. Name of the Organization: Assam Engineering College, Guwahati Geographical Location: Guwahati, India Project Title: P…… Position: Student

Background CE 1.2 The project was to develop and plan optimized pipeline for hydraulics lab congestion due to all major industries and associate buildings.( no industries around my college ) I along with my group mate decided to calculate premises which was to be located within the limits as proper plan was lacking. This project aided me in understanding the concepts of planning a pipelines, and analysis it. It has imbibed confidence in me to do engineering projects involving real time design and estimation. CE 1.2.1

CAREER EPISODE 1 In this project I have calculated friction losses of pipelines for optimized pipeline network for Hydraulics lab in college campus. To solve the problem during installations I have suggested excel designs( Excel design program was made for selecting pipes based on the practical friction losses, Please if u you could enhance it more this line ). I suggested different methods for calculating material losses and friction losses of pipeline. CE 1.2.2 My contribution in the project was: 

To design a pipeline with optimized network for hydraulics lab.



To analyze the design and calculate the friction losses.

CE 1.2.3 I designed the pipelines network by using hydraulic design and analysis of flow conditions in pipe networks are dependent upon estimating the friction factor, f (please read the line again, two different sentences are mixed in an unusual way ).The performance of its explicit formulations and those of artificial intelligence (AI) CE 1.2.4 I systematically planned out the network design as per standard design and specifications which is listed below: ( please make it sure that these are the things required for the design of pipe netwroks, I have no idea about it )      

CE 1.2.7 The knowledge on subjects relating to material and network designs came very handy in design modelling ( I have also studied hydraulics subject, fluid mechanics – if u can link them here; ); I calculated losses and analyzed designs. I made use of drawing software’s like “AutoCAD” and “Catia” for developing two and three dimensional figures and simulated virtual structure with real one. I checked with its suitability for the proposed design, its structural strength and quality.

CAREER EPISODE 1

( shouldn’t the paragraph above and below be linked, paragraph 1.3.1 CE 1.3.1 Here the flow of fluid through a pipe is resisted by viscous shear stresses within the fluid and the turbulence that occurs along the internal pipe wall, which is dependent on the roughness of pipe material. This resistance is termed pipe friction and is usually measured in feet or metres head of the fluid, as it is known as head loss due to pipe friction.

CE 1.3.2 Head Loss in a Pipe is affected by a number of factors which include the viscosity of the fluid, the size of the internal pipe diameter, the internal roughness of the inner surface of the pipe, the change in elevation between the ends of the pipe and the length of the pipe along which the fluid travels. CE 1.3.3 The valves and fittings on a pipe also contribute to the overall head loss that occurs, however these must be calculated separately to the pipe wall friction loss, using a method of modeling pipe fitting losses with k factors. CE 1.3.4 Here I have used Darcy Weisbach Formula as it more accurate to calculate pipe friction losses and it is stated as standard equation for hydraulic engineers. Weisbach first proposed the relationship that we now know as the

10

CAREER EPISODE 1 Darcy-Weisbach equation or the Darcy-Weisbach formula, for calculating friction loss in a pipe. CE 1.3.5 I have used AI techniques which include artificial neural networks (ANNs) and genetic programming (GP); both use the same data generated numerically by systematically changing the values of Reynolds numbers, Re, and relative roughness, ε/D , and solving the Colebrook-White equation for the value of f by using the successive substitution method. The tests included the transformation of Re and ε/D using a logarithmic scale. This study shows that some of the explicit formulations for friction factor induce undue errors, but a number of them have good accuracy. CE 1.3.6 The Darcy-Weisbach hydraulic equation serves as the basis for hydraulic design and analysis of water distribution systems, and it is expressed in terms of pressure drop, which is a directly measurable quantity of friction. However, the mathematical formulation of the problem includes an empirical friction parameter, f for which the Colebrook-White equation is one wellknown implicit formulation, such that the factor appears on both sides of the equation. CE 1.3.7 Here I have used GP techniques ( what is GP techniques?? ) also as it is considered for robust applications of optimization algorithms and represent one way of mimicking natural selection. These techniques derive a set of mathematical

independent and dependent variables using such operators as mutation, recombination (or crossover), and evolution. CE 1.3.8

10

CAREER EPISODE 1 In smooth pipes, friction factor f depends only on Re, the calculation are performed using different methods and tests. I calculated the head losses and flow. The energy loss due to friction in Newtonian liquids flowing in a pipe is usually calculated with the Darcy-Weisbach equation, as follows.

CE 1.3.9 I have used Moody Chart ( I have prepared charts myself by setting up an experimental model , based on that values were extracted for the design program; if u think it needs to be mentioned or if u find it unnecessary then don’t include ) to provide final method of finding an accurate friction factor and this encouraged use of the Darcy-Weisbach equation , which quickly became the method of choice for hydraulic engineers ( what is the link of this line to my project ?). Based on all calculations of head loss and friction loses I have decided the pipeline material and designed optimized pipeline network.

CE 1.3.10 Technical problems encountered: Initially, my project was fail due to improper calculations of friction losses in pipeline network selection. 

To resolve the issue, I have calculated losses using all methods of friction losses and selected the best methods for calculating losses effectively and precisely by using technical manuals provided by our project guide. Finally, I resolved the issue and completed the project successfully.

standard

specifications. I shared good rapport with the all team members. I was involved with prepared reports

and sent to higher management. (check

grammar ) CE 1.3.12 I was responsible for information flow and direction of the project and felt the tasks must be delegated enough since the timeframe given for the project was too short. Therefore, I decided to divide my project work into various phases like planning stage, implementation stage and execution phase so as to complete in the given time frame. I use s share good rapport with my team members. ( repetitive line as in the previous paragraph, please change it to something different; if required add some more to it ) CE 1.4

Summary The experience gained through practical application of the engineering subjects and an

advantage of on-site encounter with real work problems

has helped me to gain clear perspective on the theoretical concept. It emboldened my ability to analyze the situation and evaluate its pros and

CAREER EPISODE 1 cons to make sound decision and to get precise solution for the changes or request made by the client. CE 1.4.1 Working on this project was beneficial for me as I learnt a lot in terms of the analysis and design modeling of the structures. I was able to overcome numerous problems arising on site. Solving the problems gave boost to my managerial and technical skills in all aspects of designing, planning and execution of large projects. Working on this project was an extremely rich experience. My project guide, Management and team members were utmost happy for the services I have rendered them during this project.

On the

whole it was a great learning experience as well as a productive output from me as I not only met my prescribed goals but also exceeded them. (here u have mentioned about the site experience but not much written about the site; also in the report please add some more of ‘’ MY work”. Please go through the changes and also add some more content to it )
