    Newton's Cradle
    (University of New Brunswick, 2017) Turner, Aaron; Cosman, Justin; McCullum, Craig; Dr. Simoneau
    The final design report provides the final design performed by Group 12. The design includes the necessary background research on the Newton’s Cradle project as well as identifying the specifications and constraints. A feasibility study of constraint resolutions was performed and can be found in the report. The design process is outlined from initial concepts to the construction of the exhibit. The project objective is to design a fully functioning Newton’s Cradle Exhibit for Science East. As Science East is a museum, the exhibit must also provide a learning experience of the physics and mechanics that allow the Newton’s Cradle to perform the elegant motions it does. In order to complete the provided task, background research was performed to develop a clear understanding of how the product functions. After identifying the key components and design requirements of the product, constraints and design specifications were generated. An analysis was performed on these design constraints and specifications to determine solutions on how they can be resolved. In order to remain on schedule with the design process a task list and GANTT chart were created laying out the product design process. The report outlines the design process of the three components of the final design; Newton’s balls, interconnections and the frame.

    The dissolution rate constant of magnetite in ammoniated water at 140 °C and a pH25°C of 9.2
    (University of New Brunswick, 2019) Turner, Aaron; Lister, Derek
    Corrosion of carbon steel components is a major problem in the power generation industry and has been proved to be reliant on the protective magnetite oxide layer. Predicting the corrosion rates and material transport with the use of developed models has indicated the importance of a reliable value for the dissolution rate of magnetite at various chemistry conditions. In this study an impinging jet test section was placed in a high pressure recirculating water loop to measure the dissolution of sintered magnetite pellets made from synthesized magnetite powder. The dissolution experiments were conducted under typical power plant feedwater conditions in ammoniated water at pH [subscript 25°C] 9.2. The addition of film-forming amines to the coolant was also studied to determine their effect on the dissolution rate of magnetite. The findings in this study can be used to understand and reduce the dissolution and removal of the protective magnetite oxide layer, which will reduce flow-accelerated corrosion rates, fouling of heat transfer surfaces due to material transport and the level of radioactivity in nuclear power plants due to the deposition of radioactive corrosion products outside of the core.
