Meat quality. 4.1.3.1. Fatty acid composition. The fatty acid compositions of oils added to the chicken rations as an energy source in this experiment was shown in Table (3)‚ and reflection of these oils on fatty acid compositions in all meat chicken was presented in Tables (14‚ 15‚ 16 and 17). These compositions of soybean oil and palm oil (PO) were summarized in Table (3) showed that the largest amount in palm oil was oleic acid (39.8 %)‚ followed by palmitic acid content (38.42 %)‚ stearic acid

Heat transfer is a discipline of thermal engineering that concerns the generation‚ use‚ conversion‚ and exchange of thermal energy and heat between physical systems. Heat transfer is classified into various mechanisms‚ such as thermal conduction‚ thermal convection‚ thermal radiation‚ and transfer of energy by phase changes. Engineers also consider the transfer of mass of differing chemical species‚ either cold or hot‚ to achieve heat transfer. While these mechanisms have distinct characteristics

The solar energy use in Africa These days‚ solar energy has been the most talkative alternative energy source in the world. Unlike the gas‚ oil‚ and coal‚ solar enrgy is one of the clean and renewable resource‚ which can not only generate power but also protect the environment. Africa‚ has second largest population‚ estimated 1.6 billion‚ however‚ around one third of it’s people still live in the condition with no eletricity. (Renewable energy in Africa

Can alternative energy effectively replace with fossil fuels? ‘’Fossil fuels are coal‚ natural gas and petroleum.’’ (http://en.wikipedia.org/wiki/Fossil_fuel) They are all organic residues. People use this for their energy‚ fuel and heating requirements. But fossil fuels polluting environment so much and people started to think about using alternative energy for their environment’s healthy. ‘’These alternative energy resources are windy power‚ solar energy and geothermal energy.‘’ (http://en

heat exchanger is a device built for efficient heat transfer from one medium to another. The media may be separated by a solid wall‚ so that they never mix‚ or they may be in direct contact.[1] They are widely used in space heating‚ refrigeration‚ air conditioning‚ power plants‚ chemical plants‚ petrochemical plants‚ petroleum refineries‚ natural gas processing‚ and sewage treatment. One common example of a heat exchanger is the radiator in a car‚ in which the heat source‚ being a hot engine-cooling

in this report is heat transfer in a concentric tube heat exchanger. A heat exchanger is a device used to transfer heat from a hot fluid to a colder fluid. Heat exchangers are widely used in the petroleum industry for various reasons. Some of the most important reasons are theta heat exchangers increase the process efficiency‚ conserve energy‚ reduce maintenance and provide employee safety among many other reasons. The main objectives of the lab study were to determine the heat transfer rate‚ the

Oranges and Apples Apples and oranges are the world’s best fruit as I can say‚ and both of these edible elements have several things in common. Firstly oranges and apples are both fruits and they are ridiculously delicious and most of the people have them every day for healthy purposes. Another factor they have in common is that both of these fruits grow on trees. Another way that oranges and apples are alike is that they are the same in shape‚ oranges and apples take the shape of circular figure

Specific Heat and Conservation of Energy When energy in the form of heat Q is added to a material‚ the temperature of the material rises. Note that temperature‚ in units of degrees Celsius (°C) or Kelvin (K)‚ is a measure of how hot or cold a substance is‚ while heat‚ in units of joules (J) or calories (cal)‚ is a measure of its thermal energy. 1cal = 4.19J. A measure of the efficiency with which a substance can store this heat energy is known as specific heat capacity‚ or simply the specific heat‚ . The
