Only need helpt with part D please

a) What is a Carnot cycle? Firstly, describe it Answer: a) A Carnot cycle: is a reversible heat engine cycle. Carnot Cycle Process: -isentropic compression -isentropic expansion -constant temperature heat addition -constant temperature heat rejection b) What do you think a S-T diagram would look like? (Here S is the entropy and T is the temperature). Explain it and provide a plot of S vs T (you will need to justify the plot to have points). b) Answer: a temperature entropy diagram (T-S) is used for thermodynamics visualization of changes in temperature and specific entropy in a thermodynamic process, the graph is a curve. the area under the curve is the heat transferred to the system during the process; and a isentropic process is a vertical line, and a isothermal process is a horizontal line on this graph. (makes it look similar to a square graph) . the diagram that will be sent shows a thermodynamic cycle between a hight temperature reservoir ( TH ), and a low temperature reservoir (c) . in a reversible process, the area under 2c is the energy exchanged between the system and the cold reservoir. The area for W is the amount of work energy exchanged between the system and the surroundings. and QH is the amount of energy system exchanged with the hot reservoir. c) Fully derive the efficiency for the cycle. Answer C) Efficiency of carnot cycle= (heat supplied-heat rejected)/heat supplied For reverssible heat engine: n = Qs 21 22 TI T2 Wnet T1 - T2 Qs n = T1 TH - TC n = TH d) how do go from the definition of efficiency to the result for the Carnot engine
