Explain, with diagrams, the difference between open and closed thermodynamic systems and their key properties in thermodynamic applications. Evidence You must produce for this task: b. Using your understanding of energy transfer by heat and work, analyse the differences in energy-transfer mechanisms between closed and open systems by addressing relevant physical and mathematical principles. c. Derive both the No-Flow Energy Equation (NFEE) and the Steady-Flow Energy Equation (SFEE), clearly identifying all terms and underlying assumptions. d. Compare NFEE and SFEE, and discuss practical applications of each in the aviation industry (e.g., piston engine vs. gas turbine). e. Provide an example of a steady-flow device and an unsteady-flow process in real engineering applications (e.g., turbine vs. filling of a tank), and explain how the associated energy and mass interactions differ
