A Carnot cycle using 60 kg min of water, is applied to generate electrical power (at the turbine, h3- h2) and heat (at a condenser, h4-h3), between Ph=50 bar and P=1 atm. The heat necessary at the boiler (h2-h1) is obtained from the combustion of methane with excess of air at fractional conversion of methane of xch,= 0.75, giving water in the vapour phase, and under isothermal conditions (no heat is employed to heat the inlet and outlet streams). Calculate, i) The minimum volumetric flows of methane and air at the boiler. ii) The Net Work obtained from the cycle. iii) Percentage of cogeneration that can be achieved in the cycle.

An electric hot water heater consumes 3.1 kilowatts of electricity and converts it to heat. How long will it take the water heater to heat a 67 gallon tank of water from 10 degrees Celsius to 50 degrees Celsius? (1 kilogram of water is 0.37 gallons, 1 Calorie = 4200 J).

Task 1: As a maintenance manager at a plant, you are required to update the existing maintenance plan for one of the critical plant's systems. This entails defining economical and technically practical maintenance interventions while considering a high level of safety. What are the potential approaches for maintenance interventions that could be included in the current maintenance plan? Provide definitions for each of them, outline their advantages and disadvantages, and support them with real-life examples. - State two potential maintenance decision-making strategies you could adopt and clarify their steps and logic of implementation. Introduce and explain the concept of Prognostics and Health Management (PHM). Describe what PHM entails, as well as its benefits and expectations. - Explain how the frequency of planned maintenance interventions can impact production and costs for a specific component. Clarify the process for selecting the best maintenance intervention approach for that…
QUESTION 3 A Type I offshore life jacket (i.e. personal flotation device) is the type worn by commercial fishermen - it is designed for extended survival in rough, open seawater. Consider such a life jacket that uses an impermeable foam material with a density of 32 kg/m³ - the other parts of the life jacket (straps, fasteners, etc) weigh 0.6 kg and are of negligible volume to the design. a) Draw a free body force diagram for the life jacket. b) Determine the minimum volume of foam material (in L) that is needed for the life jacket in order to provide a minimum 98 N net upward force when it is fully submerged in seawater (as required by US Coast Guard regulations).

Formulate a linear program for this problem. 1) A clothing factory can make three shoe types: A,B, and C. Their profits per shoe are, respectively, $5, $4, and $3. Type A shoes require 4 pieces of leather, and 1 piece of cloth; type B shoes require 3 pieces of leather, and 2 pieces of cloth; type C shoes require 5 pieces of cloth. The factory has 10,000 pieces of leather and 50,000 pieces of cloth available. Furthermore, the factory must produce at least 500 units of each type of shoe.
