physics and chemistry‚ heat is energy transferred from one body to another by thermal interactions. The transfer of energy can occur in a variety of ways‚ among them conduction‚radiation‚ and convection. The SI unit of heat is the joule. Heat can be measured by calorimeter‚ or determined indirectly by calculations based on other quantities‚ relying for instance on the first law of thermodynamics. In calorimeter‚ the concepts of latent heat and of sensible heat are used. Latent heat produces changes of

characteristics of a Centrifugal pump. The Centrifugal pump is largely used in petrochemical industries to move liquids around the plants and refineries. Through common practise of Centrifugal pump operating characteristics is it possible to determine the optimum conditions of particular conditions. The results of typical characteristics are expressed on this work in terms of pump discharge pressure‚ pump efficiency‚ and power demand at various pump speeds of verses pump discharge.

SUMMARY This experiment has four objectives to it of which are measuring the standard performance characteristics of the pump‚ comparing the performance characteristics for three different Reynolds numbers and explaining the effects observed and to also make predictions about the performance for a pump with an impeller diameter of 228mm using the data obtained in the experiments. This experiment was conducted under room temperature. The motor was first adjusted to 3000 rpm and the input valve which

Pollution: Air‚ Water‚ Visual Pollution is the contamination of the natural environment. Pollution is one of the big issues in nowadays world. Everywhere in the planet‚ even in the most remote areas a kind of pollution can be seeing. In the air‚ in the water or in the cities the pollution is present and make places inhabitable or ugly to live in. Pollution affects‚ farms plantations‚ fishing business‚ brings sickness to people and animals that lives in polluted areas. There are several kinds of

Water‚ land and air pollution Water pollution Water pollution is usually caused by human activities. Different human sources add to the pollution of water. There are two sorts of sources‚ they mostly come from pipelines or sewers and then into the surface water. Nonpoint sources are sources that cannot be traced to a single site of discharge. Examples some sources are: factories‚ sewage treatment plants‚ underground mines‚ oil wells‚ oil tankers and agriculture‚ acid deposition from the air

Water and Air Pollution Analysis When doing the research for this project I was actually very surprised just at how much air pollution that there actually is in Bourbon County. I have always heard things like "we live in a bad community" or similar remarks because there are two big factories that put out harmful pollutants in the air. Those factories are CMC/CLA and Mallinckrodt. After reading the report that was put out by scorecard.com I realize that my community may be in more danger.

Air and water pollution affect the biotic and abiotic environment on a global scale. All pollutants affect individuals in different ways‚ but mainly affect those with asthma or underlying respiratory conditions. Transportation and energy consumption are the biggest contributors to pollution and global warming. With world population on the rise‚ carbon dioxide in the atmosphere is also climbing a steep hill. CO2‚ a primary air pollutant‚ is the most major concern amongst environmental scientists‚

Reducing Air and Water Pollution Reducing air and water pollution is always a challenge. Even in a smaller city like Enterprise‚ Alabama. So many things seem out of our control; however if everyone was to do their part‚ even if it’s just a small change‚ it can make a big difference. So many luxuries we have in our lives we take for granted‚ and so many pollutants we put into the atmosphere and our ground water without thought. I want to show that in a small town like Enterprise that does
