Abstract

This paper discusses and examines thermodynamics concepts and systems, particularly air conditioners. The principles upon which these systems are built, namely the first and the second thermodynamics laws are analyzed. Air conditioner performance and efficiency is also examined under the two laws. The second law of thermodynamics helps in determining the effectiveness of thermodynamics-based systems and is used in this paper to determine the efficiency of air conditioners. This paper finally makes recommendations based on calculations that determine the levels of efficiency of air conditioners.

The development of solar energy is based on a use of solar radiation for generation energy. Solar energy is the kinetic energy of the radiation (mainly light) formed by reactions in the solar interior. As its stocks are almost inexhaustible (astronomers counted that the Sun will “burn” some more millions of years), solar energy belongs to a renewable source of energy. In natural ecosystems, only a small part of the solar energy is absorbed by chlorophyll that contains in the leaves of plants and is used for photosynthesis, namely for the formation of organic matter from carbon dioxide and ...

The term recycling refers to the process of changing waste materials into usable, new products, thus, preventing the wastage of useful materials. It leads to the reduction in the consumption of fresh raw materials, usage of energy, water pollution, and air pollution. It obviates the need for conventional waste disposal, and the greenhouse gas emission is far less than fresh production of the product. There are several materials and wastes that can be recycled including plastics and others. Modern waste management includes recycling as a key component and is the third aspect of waste management hierarchy which includes Reduce, Reuse, ...

ABSTRACT

The environmental friendly activities have been given utmost importance in every field. Due to the environmental degradation, the new trend of “go green” has been formed among the people. The people are very persistent about sustainability. The architecture and civil engineering are one of the major fields where the sustainability has to be considered on priority basis. Architect Stefano Boeri has been translating his unique idea of sustainability through world’s first vertical forest building, Bosco Verticale. The objective of the present paper is to explore the safety, durability and the sustainability of the architecture. It these factors are ...

Introduction

Stainless steel is an alloy with iron as major part and chromium with at least 11% by weight . Stainless steel industry grew rapidly during the 1989-93 period . This paper analyzes stress corrosion of stainless steel along with prevention measures and selection methods for stainless steel. After carrying out the study, it would be established whether stainless steel is an effective alloy or not for major uses in steel industry through adopting various selection parameters. Stainless steel is called stainless due to the resistance to rusting and corrosion .

Stress-corrosion in Stainless Steel

In order to reduce various occurrences of intergranular stress-corrosion cracking and severe ...

Introduction

Energy drives the world today. The energy required today must be easily available, reliable, and affordable. Since the Industrial Revolution, fossil fuels like coal, oil, and natural gas have been the major sources of energy that have driven modern world. However, fossil fuel resources are limited, and continued dependency on them may have severe and adverse effects on the environment. Fortunately, when it comes to energy, there are alternatives. The most important, powerful and significant burns brightly in the morning sky.
Solar energy has tremendous potential and its utilization is developing quick, yet in numerous quarters it is still ...

Introduction:

The report seeks to explore the production and utilization of nuclear energy, a form of energy that is produced through a series of chemical reactions involving the atomic nuclei. In 1896, three scientists, Henrie Becquerel, Pierre Currie and Marie Curie, discovered the radioactivity in uranium salts and further pursued the experiments, and they separated radium, the highly radioactive component (Healey 37).
With advanced research, the atom came to be well defined. The terms alpha, beta and gamma decay, came into existence; that is, the release of energy when the nucleus releases neutrons and electrons in the form of electromagnetic radiation. ...

Introduction
A hybrid car is a car used to drive the drive wheels more than one source of energy.
Modern car manufacturers often resort to sharing of the internal combustion engine and an electric motor, which avoids the mode of the internal combustion engine in low loads, and also to realize the recovery of kinetic energy, increasing the fuel efficiency of the power plant. Another common type of hybrids is vehicles, in which ICE is combined with engines running on compressed air.

It should be distinguished from hybrids vehicles with electro-mechanical transmission, such as locomotives, some tractors and tanks.

[Heat Lost From a 6-Inch OD Steam Line]
Analyze heat lost from a 6-inch OD steam line. The line carries high-pressure steam throughout the factory at 400 psi, 400oF. Specify type and thickness for insulating the steam line. Compare the cost of energy lost with and without pipe insulation. You can assume steam is generated 8000 hours/year. Compare energy cost reductions based upon a gas fired boiler and a fuel oil fired boiler. Assume boiler energy input at 6.5(106) Btu/hr.

Given outer diameter OD = 6-inch, pressure = 400 psi, steam temperature = 400oF.

The following assumptions are made;

The steam pipe is made of mild steel
The ...

This paper will focus on analysis of a gas fired rotary kiln in the processing of Bentonite. A rotary kiln is a drier that is used for increasing the temperatures of materials in a process called calcinations through a continuous progression. During the processing of minerals such as Bentonite and cement, this kiln is appropriate. Its thermal efficiency ranges from 50% to 65%. This kiln has a cylinder that is slightly incline horizontally and rotates gradually about its axis. Materials that are to be processed are fed into the kiln through the upper part of the cylinder. These materials slowly move to the lower ...

In order to address the issue of increasing energy cost as a percent of revenues firstly it is important to understand what the main drivers of the change are. Variance analysis could help to evaluate the contribution of different components to the raise in energy cost to revenues ratio (Lipczynski, Wilson & Goddard, 2005). This step will help to identify areas to address or may point out the root cause of the problem that is responsible for the whole deviation. The first area to explore is the profitability of the business itself. If the problem lies in low sales, customer dissatisfaction, ...
