The document presents the calculations for a water injection system for an oil and gas production operation with 6 wells. It includes tables showing well information, maximum injection pressures for each well, pressure drops in injection pipelines and truck pipelines, pump discharge pressures, and total pressure drops and actual injection pressures. It determines that a pump with capacity of 35,400 bpd, discharge pressure of 1543 psi, 1196 horsepower, and 23 stages is needed. It also states that the annual cost to operate this system would be $402,352.46. Finally, it describes recreating the well system layout in PIPESIM software and confirming that the pressure results match the hand calculations.
An internal combustion engine generally utilizes a conventional 4 stroke process including an intake stroke, compression stroke, expansion stroke and exhaust stroke and in addition to this 4 stroke process adds a secondary process having 2 additional strokes for scavenging the combustion chamber with fresh air. This 2 stroke scavenging process employs fresh air intake stroke and a fresh air exhaust stroke to exhaust any remaining burnt and unburnt gases from the combustion chamber.
One of the most difficult challenges in engine technology today is the urgent
need to increase engine thermal efficiency. This paper presents a Quasiturbine thermal
management strategy in the development of high-efficiency engines for the 21st century.
In the concept engine, high-octane fuels are preferred because higher engine
efficiencies can be attained with these fuels. Higher efficiencies mean less fuel
consumption and lower atmospheric emissions per unit of work produced by the engine. While the concept engine only takes a step closer to the efficiency principles of Beau de Rochas (Otto), it is readily feasible and constitutes the most efficient alternative to the ideal efficiencies awaiting the development of the Quasiturbine photo-detonation engine, in which compression pressure and rapidity of ignition are maximized.
A series of Basic Koncepts and Cases covering 'General Management' spread over four presentations - simple and easy to comprehend through pictures. In case of doubts and confusions please feel free to contact me via the last slide options!! Cheers to learning!! :)

CASE STUDY: Health analysis of reciprocating engines, compressors and gas pip...Abdul Basit Bashir
This paper refers to a detailed study conducted in March 2017 by SUMICO Technologies to evaluate the mechanical performance and condition of critical reciprocating engines, compressors and associated pipelines using state-of-the-art technologies at a natural gas booster station in Mari Gas Field (Sindh, Pakistan).
Results of the study revealed various hidden areas requiring attention to increase efficiency, reduce operational costs and increase reliability of the plant. This paper describes the technologies used, performance parameters analyzed,some interesting findings and the benefits gained through the study.

Jean-Paul Gibson: Analysis Of An Open Feedwater Heater SystemJean-Paul Gibson
People often look surprised when I tell them that Thermodynamics was probably one of my favorite classes in school. This was the final project for my Thermo II class and was intended to be done in groups. I wanted to challenge myself to a near unnecessary limit by completing this entire project myself. The purpose of this project was to determine the optimum operating pressure for the feedwater heater for a power cycle (from a selected problem in the textbook). However the primary focus, and most difficult task, was writing a program in C++ to calculate multiple values for a selected problem in our textbook. I quite literally had to teach myself how to program in C++ well beyond the basics I had learned in an intro class. This program had to be capable of cross referencing multiple reference tables in the back of the book, each having dozens of values which had to be manually typed in. Which reference tables it pulled values from was dependent on the user inputted turbine efficiency and feedwater heater pressure. It easily took me over a month to debug and test this program to ensure it was always going to the correct reference tables to pull data when outputting the calculations it performed.
Update on 7/2/2016: I did attempt to make another program that would allow the user to type in any feedwater heater pressure rather than make a selection from values there was a reference table for in the back of the back. The program used a method of interpolation to obtain all the data needed to perform all the calculations that were outputted. I don't remember the last time I attempted to run that version of the program, but I seem to recall getting impossible answers outputted. This indicated to me that a more complicated method of interpolating values was required, or I just couldn't get it to work correctly. I ultimately decided against pursuing that version of the program any further. Just getting it work correctly with a predefined list of pressures to select from was difficult enough.
Designing of sprinkler irrigation systemEngr Mehmood
Sprinkler irrigation is a method of applying irrigation water that is similar to natural rainfall. Water is distributed through a system of pipes usually by pumping. It is then sprayed into the air through sprinklers so that it breaks up into small water drops that fall to the ground.
