Nuclear Energy Essay

Thermal effect results from the change in the heat capacity of the gases in the combustion chamber. It is worth mentioning that EGR contains water and CO2 which have higher specific heat capacity than air. The change in absorbing heat is proportional to the added mass, to the heat capacity at constant pressure and to the difference in temperature between the EGR and the combustion temperature. ΔQ=Δm*Cp*(Tcom-Tegr) The change in specific heat capacity results from charge dilution and represents…

Particle: Work and Energy and Planar Kinetics of a Rigid Body: Work and Energy. Kinetics of a particle: work and energy shows the particle moving when forces are applied to it and produces work and energy. Meanwhile under planar kinetics of a rigid body shows the rigid body on the plane when forces are applied and produces work and energy. There are similarities and differences between both of it. Kinetics of a particle Planar kinetics of a rigid body Similarities - Conservation of energy -…

2.1. Theoretical Background 2.2. Material Selection Material selection plays an important role as the humidifier has to deal with a pressure of 2 Bar and temperature ranging from ambient to 90oC (maximum) and have to bare a load of 80 Newton. Simultaneously it should be lighter than aluminum and should be cheaper and fabricating time should be less and it should be capable of mass production and before all this it should serve the purpose. when developing plastic parts. Selection of an…

that by increasing the amount of I- increases the rate of the reaction, while increasing the temperature also increases the rate of the reaction. The reason I- increases the rate of the reaction because it is a catalyst and it lowers the activation energy, which allows the reaction to occur faster. This result can be supported by a study that was done on hydrogen peroxide, which determined that H2O2 decomposition increased with temperature and catalyst loading (Shang, Noel, & Hessel, 2017). In…

3.3.2. Initial and Boundary Conditions. The pipe is subject to atmospheric pressure Po at time zero this represented initial condition . Boundary condition represented as at the pipe inlet profiles, uniform pressure Pinlet and its value change with concentration of nanofluid [φ%] and inlet temperature T0 = 60 ºC can be measured for all experimental . On the pipe wall, the pressure was atmospheric pressure Po . Moreover, flow and thermal fields are assumed symmetrical with respect to…

in resistivity may also be due to the increase in activation energy (Table 2) with increase in Cr concentration. This increase in activation energy indicates that the Cr ions entering into octahedral sites impedes the electron hopping between Fe2+ and Fe3+ ions for electrical conduction by occlusion of Fe2+ and Fe3+ transformation. This led to an increase in resistivity and a decrease in the conduction. The value of activation energy from table 2 indicates that the conduction process in the…

Presentation of non-conventional welding procedures applied a. Friction welding Friction welding is a pressure welding procedure, at which the energy necessary for welding is obtained by transforming the friction mechanical energy into heat. [1] Welding process includes the following phases: [1]  driving one of the welding components in rotating, with constant or variable speed and the other one (fixed) pressing on it, with an axial…

1. OBJECTIVES The objectives of the experiment are: • Measurement of creep deformation in 2 materials; lead and polypropylene at room temperature. • Determine how creep deformation of chosen materials can be affected by stress. • Recognise that the two classes of materials show differences in creep behaviour. • Awareness of creep as a design consideration. 2. THEORY 2.1 Introduction Structural materials are often placed in service under a certain applied load at elevated temperatures (eg. wind…

it is not fair to compare the two systems based purely on the magnitude of its COP as the work required in a VA refrigerator is produced by heat, it is much cheaper than the work required in VC refrigerator which require electrical or mechanical energy. Environmental issue Conventional VC refrigerant such as CFC or HCFC can deplete the ozone layer and is already phased out based on the Montreal Protocol. Modern VC refrigerant like HFC - also known as f-gases (fluorinated greenhouse gases) - has…
