Potential energy

(2) through transposing Eq (2) The activation energy was found from the following equation E = 8.314 * slope (3) The activation energy values were later used for computing the pre-exponential factors (A) by equation (1). In the meantime, activation energies (Ea) for these energetic compounds were calculated by the Ozawa method. The Ozawa equation according to ASTM E698 is equal to…

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 no ozone depleting property but has high global warming potential (GWP) and its use is being reduced and phased down by the EU f-gases Regulation No…

Mathematical model Heat and mass transfer properties of counter flow wet cooling tower are obtained through the balance of mass and energy equations. The assumptions made for deriving the governing equations are listed below [14, 15]: • Heat and mass transfer take place only normal to the flow direction. • Heat transfer to the environment through the walls are negligible. • Heat transfer from cooling-tower fan is negligible. • Specific heats of water and dry air are constant. • Heat and mass…

character, dissimilar to sugars that can just safeguard body capacities for a couple of minutes. Fat gives the primary fuel source to long length of time, low to direct power exercise. (Quinn, 2014) “Other types of fats found in the body serve non-energy-producing functions. Phospholipids are a key structural component of all cell membranes and form protective sheaths around some large nerves. Steroids are found in cell membranes and also function as hormones or as building blocks of hormones…

What energy system(s) does the Wingate Test rely? Explain. The energy systems that the Wingate test relies on, is glycolysis and ATP-PCr. Anaerobic power is used for high intensity, short duration exercises, and activities. The Wingate test is anaerobic, which will utilize fuel through glycolysis and the ATP-PCr system. The Wingate test is very short in duration, and high in intensity, which means oxygen is not present in this process. The ATP-PCr system breaks down ATP into ADP for energy. This…

are thin and therefore more aerodynamic and will help the velocity and speed of the car. Then with the pens being hollowed out, it helps with the air and power from the mousetrap to flow through the pen which is attached to the wheels and helps the energy be sent to the wheels and thus, making the car move forward. When designing the car, we chose to use eye hooks because tape and glue would help with the sturdiness and help keep the mousetrap and the wheels connected without breaking. With the…

additive prepared with different percentages(0,15,25,35 and 45) wt.% and different thickness. The experimental results showed that the D.C electrical conductivity increased with increasing the alumina concentrations and temperature. Also the activation energy change with increasing of additional alumina. The dielectric constant, dielectric loss, A.C electrical conductivity are changed with change the concentration of the filler and frequency of applied electrical field. Keywords: Composites,…

about what I study and what I do, and I use that passion to drive my work ethic. My goal has always been to achieve to the best of my ability and to know that I am doing my absolute best in every situation, whatever the domain. I strive to reach my potential and to know that there was nothing more I could have done to improve. As one of my friends described, a large part of my best self is “your drive and ambition to get things done, something which you more than anyone else has.” I am…

with the environment (Akin, 2011; Kemp & Krockenberger, 2002;). In Biomimicry, through studying thermoregulation, human beings can apply nature’s techniques to architecture when designing buildings. Present temperature systems are using a lot of energy, especially to control heat and cooling loads. (Carpi 2010). Thermoregulatory mechanisms include passive thermoregulation and active thermoregulation; by studying butterflies and birds more effective climate systems can be developed, leaving a…

CHAPTER 2 2.1 ELECTROCARDIOGRAM The ECG Signal is a graphical representation of the electromechanical activity of system. The various propagation action potentials within the heart produce a current flow, which generates an electrical field that can be detected, in significantly attenuated form, at the body surface, via a differential voltage measurement system. The resulting measurement, when taken with electrodes in standardized locations, is known as the electrocardiogram. The ECG signal is…
