![]() ![]() Students are required to solve for all stream enthalpies, as well as the work needed to power the compressor and heat removed from the external system. Deadline D is the final submission and is designed to ensure students understand the full refrigeration cycle. This deadline makes sure that students know how to import their data, receive user inputs and complete data validations, and use temperature inputs for two saturated streams in order to determine enthalpy of these streams. Deadline C is focused on making sure students understand how their handwritten solutions and algorithms translate into MATLAB. Students must be able to know how the user inputs provided allow them to solve for all remaining unknowns in the system. While deadline A had students perform energy balances on each individual piece of equipment, deadline B forces students to make an algorithm for solving the entire problem. Finally, the students - Engineering Analysis (EA) Section - deserve my special grati- tude. Deadline B is used to assess how well students understand the interconnectedness of the refrigeration cycle. This manual reects the ongoing eort of the McCormick School of Engineering and Applied Science leading by Dean Stephen Carr to institute a signicant technical computing in the Engineering FirstR 2courses taught at Northwestern University. Many years ago, students wrote their own programs, first in the FORTRAN programming language, then in languages like MATLABĀ®. Furthermore, it requires that students understand the equipment involved in the refrigeration cycle and how the first law of thermodynamics can be applied to each piece of equipment and simplified in order to complete an energy balance. Chemical engineering students and chemical engineers are being asked to solve problems that are increasingly complex, whether the applications are in refineries, fuel cells, microreactors, or pharmaceutical plants. Deadline A is used to assess student knowledge of the first law of thermodynamics. A short description of each rubric and how they relate to the goals is provided below: The goals of the activity are assessed using the rubrics provided. Furthermore, this project requires students to be able to take physical and chemical laws and apply them to a system boundary in order to solve for unknowns. The technical skills that students are expected to have going into this project are mostly related to concepts learned in calculus, such as the evaluation of integrals. It allows students to learn that MATLAB can be used to aid their chemical engineering studies, and allows them to relate the concepts they learn in MATLAB to real-world problem solving in the context of chemical engineering. MATLAB is mainly used as a problem-solving tool for this project. The refrigeration cycle and the role that condensers, heat exchangers, expansion valves, evaporators, and compressors play in it chemical-engineering Star Here are 30 public repositories matching this topic. The difference between state and path functions Learning the first law of thermodynamics and how to apply it to a defined system or piece of equipment to perform an energy balance Ideally, all new concepts the students learn are strictly related to thermodynamics.
