5.2.2.2 Interpretation of Regression Model The above equation can be written as D ∝ P^0.058/(V^(-0.117) 〖D_b〗^(-0.133) ) By observing the above equation we can say that the LAZ Depth is directly proportional to the Laser Power and inversely proportional to the Scan Velocity and Beam diameter. The observations of the model can be summarized as below: As Laser Power increases the LAZ Depth of workpiece surface will also increase. This is because the heat input to the workpiece is increasing…

Everyday, people make choices that intentionally or unintentionally change the course of their and other people’s lives. These choices are ones that change the way the decision makers are seen, and the way that that person continues through life. Choices like these can be found in short stories especially, usually in order to make a statement or convey a theme efficiently. In a short story written by Tom Godwin examined here, a captain of a starship makes the choice to kill a young girl to avoid…

The reaction between sodium thiosulphate and hydrochloric acid forms the word / chemical equation below: sodium thiosulphate + hydrochloric acid -> sulfur dioxide + sulfur + water + sodium chloride Na2S2O3 (aq) + 2HCl (aq) -> SO2(aq) + S(s) + H2O(l) + 2NaCl (aq) When sodium thiosulphate reacts with diluted hydrochloric acid, a mixture of…

concentration of the the crystal violet and hydroxide ions. Using the integrated kinetics method, the rate law can be calculated for single reactant when converted to products, as well as the value of the rate constant, K, by the integrated rate law equations: Zero Order: First Order:…

Application of Bernoulli’s Equation to Fluid Dynamics Bernoulli’s equation has been used widely in an engineering aspects, the conservation of energy is the most famous one. This paper will talk about the application of Bernoulli’s equation to fluid dynamics. Fluids flow can be in different forms, such as water in the ocean, blood within our body and etc. Thus, it is necessary to study the mechanism of fluids. In the year of 1738, Daniel Bernoulli published a book called Hydrodynamica, which…

The solution of the Frank and Doris race problem looked to be simple at first. Although Doris speed began faster, Frank gained speed and passed her and thus seemed to be the winner of the race. After looking more closely at the problem I discovered this was not quite the case. I first sketched Frank and Doris given values onto the one Velocity-Time graph. Originally looking at this graph, it looks as if Frank passes Doris at 10 seconds, because that is when his speed becomes greater than Doris’s…

Often, family law courts in St. Louis, and throughout Missouri, order child support for parents who have never been married, or those who are divorced. These monetary payments are typically made from noncustodial parents to custodial parents. They are ordered to ensure that both parents bear the financial responsibility of raising their children. While most people who are ordered to make such payments comply, there are those who fall into arrears. This may be by choice, or due to unavoidable…

temperature of their surroundings. Cricket chirping falls under an equation called the Arrhenius equation which is that the higher the temperature, the faster a given chemical reaction can occur. The Arrhenius equation, in a deeper explanation, says that at higher temperatures, the probability of two…

(2.3) The equations of motion, heat and volumetric nanoparticle fraction are written in both regions as follows [22]: 1- In the Porous Region (1): The incompressibility condition yields . (2.4) The conservation of momentum requires . (2.5) The conservation of energy yields (2.6) The equation of the volumetric nanoparticle…

Reflection on True or False Equation Routine After watching the True or False Equation Routine, I have concluded that each one of the NCTM Process Standards was met throughout the video. During the video, students used communication to explain themselves and their thought process. Students had to organize their mathematical thinking and could do this through partnered discussions and whole group discussion. The second standard that this video met was reasoning and proof. I noticed that each…
