Secondary treatment of pm

Machining:  Sintered parts do have some porosity and it is, therefore, necessary to differentiate their machining behaviour from those of fully dense wrought products. The major differences are, as follows: (i) when a porous metal is machined, the depth of work hardening is more important than for the wrought metal, as in case of former, pores create stress concentration. (ii) The temperature at the tool end causes oxidation of the ...

Main Features of Pump and Pumping Systems

INTRODUCTIONThis section briefly describes the main features of pumps and pumping systems. What are pumps and pumping systems?Pumping systems account for nearly 20% of the world’s electrical energy demand and range from 25-50% of the energy usage in certain industrial plant operations (US DOE, 2004).Pumps have two main purposes:1. Transfer of liquid from one place to another place (e.g. water from an underground aquifer into a water storage tank)2. Circulate liquid around a system ...

Design and Performance Evaluation of an Ice Block Making Machine

ABSTRACTThe ambient temperature of tropical countries like Nigeria is as high as 40oC during the dry season. This ultimately gives rise to increase in demand for ice which is used to reduce the temperature of water, soft-drinks as well as other uses. This increase in demand for ice block makes the design and construction of a machine which can be used for the production of ice within a short period of time in order to save energy and time imperative and a worthwhile venture. This paper presen...

Technical report on the fabrication of a fan blade

ABSTRACTIn recent times, most of the household appliances are using electric power and as such, electricity shortage has become a major problem throughout the world. Ceiling fan is one of such appliances that consume electric power. The best way to minimize the power consumption of the ceiling fan is to reduce the weight of the ceiling fan blade. Thus, this project work entails the design of a new ceiling fan blade in which case the weight and power consumption was compared to the Panasonic m...

Advanced Fine Finishing Process

ABSTRACTThis technology is so helpful in our everyday life. This paper dealt extensively about the latest technology which is useful for finishing materials with a very high precision. These latest processes are known as Advanced Fine Finishing Processes. In this paper, we gave a thoroughinsight into some of these processes.With the demand of stringent technological and functional requirements of the parts from micro- to nano-meter range, evolution of ultra-precision finishing processes becam...

Thermodynamic Principle Of Energy Conversion

ABSTRACTEnergy conversion engineering (or heat-power engineering, as it was called prior to the Second World War), has been one of the central themes in the development of the engineering profession. It is concerned with the transformation of energy from sources such as fossil and nuclear fuels and the sun into conveniently used forms such as electrical energy, rotational and propulsive energy, and heating and cooling. A multitude of choices and challenges face the modern energy conversioneng...

GENERAL OVERVIEW OF RENEWABLE ENERGY

ABSTRACTThe rapid increase in energy consumption particularly in the past several decades has raised fears of exhausting the globe’s reserves of petroleum and other resources in the near future. The huge consumption of fossil fuels has caused visible damage to the environment in various forms. Approximately 90% of our energy consumption comes from fossil fuels. Due to industrializations and population growth our economy and technologies today largely depend upon natural resources, which are...

An Overview Of Remediation Techniques Of The Environment

ABSTRACTOil spillage which can simply be referred to as the release of oil into the environment (land or water) either through a deliberate act, accident or as a result of equipment failure indeed has an alarming effect on the affected communities due to the fact that it either renders the environmentuseless or sometimes take a longer time for the affected area to have a natural process of attenuation.In addition, having given the necessary compensation to the affected communities in line wit...
