What are the typical characteristics of those processes most likely to benefit from Model predictive control and What type of inverse of the dynamic matrix β is used for control action computation?

The gases behave as ideal at low pressure, however, at high pressure they deviate from the ideal behavior. Compare the input power required(in kW)for compressing oxygen gas by first assuming ideal behavior then the real behavior. Take inlet state at 10 MPa, 14°C and the final state after compression is 15 MPa, 127°C. You can ignore the effect of gravity and motion of the system.Assume mass flow rate of the gas as 9 kg/min

Planning is underway for a new hydroelectric power plant, and you have been asked to provide an engineering opinion on the best site for the power plant to be located. Two main sites have been identified for the plant. Site 1 is located at the base of a dam wall, with the waterline located 70 m above the turbine. The location has good accessibility for the construction crew, meaning that they are able to bring in a state-of-the-art turbine-generator system. The overall efficiency of the system is 85%, while the efficiency of the turbine alone is 92%. The geology of the area means that a 1.4 m diameter feedpipe can be installed, through which water can be supplied to the turbine at an average velocity of 6 m/s. Site 2 is also located at the base of a dam wall, with the waterline located 100 m above the turbine. Accessibility to this site is not as good as for Site 1, and as such there are restrictions on the type of turbine-generator system that can be installed. While it will be possible to use the same generator as would be used at Site 1, an alternative turbine is required. The identified turbine has an efficiency of 89%. Additionally, because of the more complex geology, a narrower feed pipe can be drilled (diameter = 0.8 m), through which water is supplied at a higher average velocity of 13 m/s. A further consideration is that the cost of distributing power from the two sites is slightly different. Power can be distributed from site 1 at a cost of $0.053/kWh, while the cost of distribution from site 2 is slightly lower at $0.051/kWh. To be competitive in the market, the company intends to retail its hydroelectric power for $0.10/kWh Provide an engineering opinion (of no more than six sentences) as to which site is superior for locating the hydroelectric plant. Your opinion should cover: • Any relevant assumptions you have made • Any thermodynamic considerations (relevant energy balances, etc.) • The power available from each site • The amount of power generated by the proposed plants • The profitability of the proposed plants • Advice as to which site is better for situating the power plant and why

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.

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.
