R Value: Wall: 0.961m2k/w Floor: 0.676m2k/w Roof: 0.7465m2k/w In a table format show with calculations and research how much money you can save by installing a 115mm layer of insulation (R2.9) in your walls, floor and ceiling over a 5 and 10 year period. Consider the capital costs. Hint: State the current R value of each component. Convert to U value. Calculate new R value of each component (walls, floor and ceiling). Convert to U value. Use Q(W)=A*(change in U)*temperature change. Determine price for installation of new insulation. Determine price saved based on less heat loss through each component separately, then add all values together, and calculate per 5 years and per 10 years. Present all of this information in a table. You do not need to draw any diagrams, simply add the R value in series with your current components R values. Assume the energy cost is 25 cents kWh
To maximize production and minimize pumping costs, crude oil is heated to reduce its viscosity during transportation from a production field. (1) Consider a pipe-in-pipe configuration consisting of concentric steel tubes with an intervening insulating material. The inner tube is used to transport warm crude oil through cold ocean water. The inner steel pipe (k, = 45 W/m-K) has an inside diameter of D;, 1 150 mm and wall thickness f; = 20 mm while the outer steel pipe has an inside diameter of D; 2 = 250 mm and wall thickness t, = tị. Determine the maximum allowable crude oil temperature to ensure the polyurethane foam insulation (k, between the two pipes does not exceed its maximum service temperature of Tp. max = 70°C.
