10.4 Five life cycle modules involved in washing a cup in a standard size residential dishwasher are shown in Figure 10.14. For simplicity, many operations, emissions, and resources are not included, and flows are reported with only one or two significant figures. The utility mix (75 percent coal, 25 percent natural gas) is somewhat arbitrary, while a 10 percent loss in transmission and distribution is typical. (Developed by Dr. Laura Wood.) 1. Write down the technology and intervention matrices for the life cycle of a glass cup 2. Assuming that a single glass cup is used 800 times, determine the corresponding final demand, and calculate the life cycle emissions. Determine the scaling vector and draw the corresponding life cycle network diagram. You may assume that one dishwasher load is 80 cups
