Abstract: The main purpose of the HVAC system is to achieve clean indoor air quality and human comfort (thermal comfort), there are many HVAC systems a designer or owner has the option to select based on the factors such as the type of the building, architecture, location, shape, surrounding climate, occupancy, envelop, level and frequency of activities, and the system operation schedule. In addition to […]
The purpose of the study was to obtain the relation between the flight time and launch height of a balsa glider of different wing area. Also the effect on flight time was recorded by changing the position of wings of the gliders. In the first part of the experiment the gliders were launched from four different height and the flight time was recorded. The experiment […]
Tribology has been there since the beginning of recorded history. Tribology is the word basically derived from Greek in which ‘tribos’ means rubbing. From this we understand that “Tribology is the scientific study of interacting surfaces and of related subjects and practices”. [1] The 3 factors that are considered to be a major factor in tribology are friction, wear and lubrication. Friction is defined as […]
Since the time when the internal combustion engines were devised, it continued to develop as our cognition of engine processes has increased, as new engineerings became available, as demand for new types of engine arose, and as environmental constraints on engine apply changed. Internal combustion engine, and the industries that develop and manufacture them and support their use, now play a dominant role in the […]
Law enforcement agencies have utilized fixed wing and rotor wing aircrafts to help enforce laws since the 1920s. This paper will discuss the advantages and disadvantages of fixed wing and rotor wing aircrafts. Take a brief look at some of the missions and technical equipments that are utilized by law enforcement agencies. Look in depth at two of their fix wing aircrafts utilized and how […]
INTRODUCTION An alloy is a partial or complete solid solution of one or more elements in a metallic matrix. Complete solid solution alloys give single solid phase microstructure, while partial solutions give two or more phases that may be homogeneous in distribution depending on thermal heat treatment. Alloys usually have different properties from those of the component elements. Alloying one metal with other metal(s) or […]
Traffic Light Controller Using 8085 Microprocessor Aim The main aim of this project is to design a Traffic light controller using 8085 microprocessor, interfacing with peripheral device 8085, and program implementing the process. Introduction The 8085 Microprocessor is a popular Microprocessor used in Industries for various applications. Such as traffic light control, temperature control, stepper motor control, etc. In this project, the traffic lights are […]
The major aim of the project is to investigate about the new hydraulic system of a380 and the reasons for increasing the hydraulic pressure from 3,000 psi to 5, 000 psi. The project is also intended at discussing and investigating about the new electro- hydrostatic actuators which uses this high hydraulic pressure. This report emphasis’s on how this hydraulic system with 5,000 psi works and […]
2.1 introduction 2.1.1 Introduction of pile Piles are the very common elements in a foundation. Pile foundation have the function that transfer loads from superstructure through through water or through the weak compressible strata, onto rock, less compressible soils or onto stiffer. This type of foundation need to carry uplift loads when it is used to support tall structures. Not only that, it is also […]
Explain in detail, the differing operating cycles inherent in two unrelated i.c (internal combustion) engines An internal combustion engine differs in operation depending on which fuel it is being run of because petrol and diesel have different properties. Diesel And Its Properties Diesel is obtained from crude oil via 3 processes separation, upgrading and conversion The initial boiling point for diesel is around 125 degrees […]
