A shrink-fit process has been used to enhance the pressure carrying capacity of a cylinder. During the process, two concentric cylinders are shrunk fitted together to form a composite open-ended cylinder. Before the shrink-fit process, the inner cylinder has an inner radius of 50 mm and outer radius 75.025 mm, while the outer cylinder has an inner radius of 75 mm and outer radius of 150 mm. Both cylinders are made of steel with Young’s modulus E = 200 GPa, Poisson’s ratio  = 0.28, and yield stress Y = 600 MPa. Due to the shrink-fit process, an interface pressure (or shrink-fit pressure), Pc = 16.9 MPa, develops at the interface between the two cylinders.

(a) Determine the magnitude of the stresses at the inner surface of the inner cylinder and at the inner surface of the outer cylinder due to the shrink-fit process.

A fuel gas consists of 75% butane (C4H10), 10% propane (C3H8) and 15% butene (C4H8) by volume. It is to be fed to the combustion chamber in 10% excess air at 25ºC, where it is completely burnt to carbon dioxide and water. The flue gases produced are to be used to generate 5 bar steam from water at 90ºC.

(REGENERATIVE CYCLE WITH ONE CLOSED AND ONE OPEN HEATER): Do not use your Steam Tables. Refer to the H2O properties given in the table below.

A regenerative cycle with one stage of reheating is executed with steam expanding initially from 20 Mpaa and 540 deg C. The reheater pressure is 10 Mpaa. The steam leaves the reheater at 540 deg C. Steam is bled after reheating to one CFWH and on one OFWH a pressure equal to 5 Mpaa and 1 Mpaa respectively. The condensate of the steam used in the CFWH is routed to the OFWH through a trap. The CFWH has a Terminal Difference of 4 deg. C. Condensation occurs at 60 deg C. Sketch the equipment and TS diagram. Isentropic expansion and compression efficiencies are 90 %. nk = 80%.

Based on the above bucket list: Please answer below questions:

1. How do the wishes/goals on your bucket list relate to your values and identity? How would they help you achieve “ego integrity”? Are some wishes/goals more important in terms of fulfilling ego integrity than others, and if so, why? Discuss specific examples from your bucket list. Describe ego integrity in your response before applying it.

2. What other developmental tasks or conflicts from Erikson’s psychosocial theory are reflected in your wishes/goals? If you haven’t yet resolved some of the tasks from earlier stages in your life or your current stage in life, you might find that you have a wish/goal that relates to fulfillment of the task. You can consider any stage, such as identify vs. role confusion (the task for adolescence), intimacy vs. isolation (the task for young adulthood), and generativity vs. stagnation (the task for middle adulthood). Make sure to relate specific wishes/goals from your bucket list to specific developmental tasks.

3. Do you think you will have the same bucket list a decade from now? What about two decades from now? Why or why not? When answering these questions, assume that your wishes/goals have not yet been fulfilled.
