This document discusses power in single-phase AC circuits and power factor correction. It begins by explaining how power (P=VI) is transmitted from generators to loads through power systems. For a predominantly inductive load, the power consists of useful power equal to VmImcosφ and useless reactive power equal to VmImsinφ. Power factor correction aims to minimize the reactive power portion, thereby improving transmission efficiency.
The document describes a numerical simulation of flow through a centrifugal pump impeller. Hassan Adel Talaat El-Sheshtawy conducted 3D CFD simulations using ANSYS/CFX to analyze the flow field and evaluate the slip factor. The simulation results agreed well with the design performance curve, especially near the best efficiency point. Several empirical slip factor correlations were compared to the numerically obtained slip factor. The effects of adding splitters and increasing the number of blades on slip factor, head rise and hydraulic efficiency were also investigated. It was found that while slip factor improved with more blades or longer splitters, hydraulic efficiency did not always increase due to additional losses.

Effect of tool size on fracture and fatigue behaviors of friction stir spot w...Dustin
The document investigates the effects of tool size on fracture and fatigue behaviors of friction stir spot welds of 6061-T6 aluminum sheets. Three tools of different sizes (T1, T2, T3) were used to make welds at different welding parameters. Quasi-static tensile tests were performed to evaluate failure strengths and modes. Fatigue tests under cyclic opening conditions found that failure lives and modes depended strongly on tool size and applied load. Fracture surfaces and microstructures of the welds before and after failure were examined using optical microscopy and SEM. The results indicate that failure strengths, lives and modes show significant dependence on tool size and processing conditions.

Applications of artificial Intelligence in Mechanical Engineering.pdfAtif Razi
Historically, mechanical engineering has relied heavily on human expertise and empirical methods to solve complex problems. With the introduction of computer-aided design (CAD) and finite element analysis (FEA), the field took its first steps towards digitization. These tools allowed engineers to simulate and analyze mechanical systems with greater accuracy and efficiency. However, the sheer volume of data generated by modern engineering systems and the increasing complexity of these systems have necessitated more advanced analytical tools, paving the way for AI.
AI offers the capability to process vast amounts of data, identify patterns, and make predictions with a level of speed and accuracy unattainable by traditional methods. This has profound implications for mechanical engineering, enabling more efficient design processes, predictive maintenance strategies, and optimized manufacturing operations. AI-driven tools can learn from historical data, adapt to new information, and continuously improve their performance, making them invaluable in tackling the multifaceted challenges of modern mechanical engineering.
Gas agency management system project report.pdfKamal Acharya
The project entitled "Gas Agency" is done to make the manual process easier by making it a computerized system for billing and maintaining stock. The Gas Agencies get the order request through phone calls or by personal from their customers and deliver the gas cylinders to their address based on their demand and previous delivery date. This process is made computerized and the customer's name, address and stock details are stored in a database. Based on this the billing for a customer is made simple and easier, since a customer order for gas can be accepted only after completing a certain period from the previous delivery. This can be calculated and billed easily through this. There are two types of delivery like domestic purpose use delivery and commercial purpose use delivery. The bill rate and capacity differs for both. This can be easily maintained and charged accordingly.

Prediction of Electrical Energy Efficiency Using Information on Consumer's Ac...PriyankaKilaniya
Energy efficiency has been important since the latter part of the last century. The main object of this survey is to determine the energy efficiency knowledge among consumers. Two separate districts in Bangladesh are selected to conduct the survey on households and showrooms about the energy and seller also. The survey uses the data to find some regression equations from which it is easy to predict energy efficiency knowledge. The data is analyzed and calculated based on five important criteria. The initial target was to find some factors that help predict a person's energy efficiency knowledge. From the survey, it is found that the energy efficiency awareness among the people of our country is very low. Relationships between household energy use behaviors are estimated using a unique dataset of about 40 households and 20 showrooms in Bangladesh's Chapainawabganj and Bagerhat districts. Knowledge of energy consumption and energy efficiency technology options is found to be associated with household use of energy conservation practices. Household characteristics also influence household energy use behavior. Younger household cohorts are more likely to adopt energy-efficient technologies and energy conservation practices and place primary importance on energy saving for environmental reasons. Education also influences attitudes toward energy conservation in Bangladesh. Low-education households indicate they primarily save electricity for the environment while high-education households indicate they are motivated by environmental concerns.
