sources to bring back the system up and to be efficient. The goal of the design phase is to understand the required key factors which has the influence to design the new product and to identify the potential risk associated with it. The Yield surface modelling helps to design the system such that Cpk associated with three factors which portraits the confidence and safety associated for the design. Also Cpk helps in design process due to its high tolerance for each factors which was useful…

Introduction Since the management team decided to assess the effective factors on the quality of the welding in the manufacturing process by utilizing simulation, we have to briefly describe the used simulation process called Design of Experiment (DOE) and understand the characteristic of such analytical process. Basically, the process of accumulating the data based on the observations is time-consuming and costly and miscalculation in the return of investment on the improvisation can be…

Critical review process of improving the Product reliability by using DFSS and DOE Introduction: In this case it all about the using the DFSS (Design for Six-Sigma) and DOE (Design of Computer Experiments) technique to improve the product reliability through developing substrate development effort for a new product with the large scale technology. Thomas Bertels and Arne Buthmann given that this is a process for developing a technology to make the smaller medical devices in a medical company…

In this lab, the guiding question is “How does the surface tension and relative intermolecular forces compare between certain substances?” In order to fully understand this guiding question, we have to know what is the surface tension and intermolecular force. The definition of surface tension is “the inward force, or pull, that tends to minimize the surface area of a liquid, and the definition of intermolecular force is the force, or pull, between the molecular which has polar…

they know which soda to drink that has less carbonation and doesn’t spew the most. Finally, the most important three topics you will need to know about is carbonation, pressure, and surface tension. These are the three topics you will need to know to do this project, carbonation, pressure, and surface tension. Carbonation is the water into…

the substance that also have dipolar characteristics. The cohesion of the water also is important because it creates the surface tension of the water. The addition of foreign liquids and objects like alcohol or table salt has an affect on the adhesion, cohesion, viscosity, density and surface tension of the water. Called a colligative interaction this weakens the surface tension and reduces the adhesion with the other substances. The materials used in this experiment was pencil, clipboard,…

Coke, the surface of the Mento allows carbon dioxide bubbles to form, as this happens the Diet Coke “explodes” out of the bottle (Hiskey). This reaction can result in large geysers of Diet Coke. As the Mentos candy sinks, carbon dioxide bubbles form on the surface, more and more bubbles from until they eventually shoot out of the bottle (Science Buddies). This experiment is well known and many people have done it before, but most do not know the reactions that cause the geysers. The surface of…

Evaporation Model, Kohler modification and Surface Phenomena The process of microdroplet evaporation is associated with the mass and heat transport through the microdroplet surface [1,2] . [2]: [ 1] Where a is the droplet radius, Pa and Pcc are the saturated vapor pressures near the droplet surface and far from the droplet respectively. Ta and Tcc are the temperatures at the microdroplet surface and the reservoir. D is the diffusion constant of vapor in the ambient gas. M and are the…
