Our engineering team developed a hypothetical hourly water consumption diagram. For one astronaut: Hour Hourly Water Consumption (gal/hr/cap) Cumulative Water Consumption (gal/cap) 1 0 0 2 0 0 3 0 0 4 0 0 5 0 0 6 0 0 7 5 (Bathroom Uses and preparing food) 5 8 0.53 5.53 9 0.45 5.98 10 0.64 6.62 11 0.5 7.12 12 0.38 7.5 13 1.6 (preparing food) 9.1 14 0.57 9.67 15 0.58 10.25 16 0.47 10.72 17 0.35 11.07 18 0.53 11.6 19 1.6 (preparing food) 13.2 20 0.5 13.7 21 28.00 (Shower and Bathroom Uses) 41.7 22 0.3 42 23 0 42 24 0 42

For 150 astronauts The astronauts are divided into 3 groups, 50 people each. They take turns sleeping, with shifts from 10pm-6am, 6am-2pm, and 2pm-10pm, and each group’s schedule is shifted by 8 hours; this effectively allows them to stagger their water use. Hour Hourly Water Consumption (gal/hr/cap) Cumulative Water Consumption (gal/cap) 1 120 40 2 175.5 98.5 3 315 203.5 4 132 247.5 5 4440 1727.5 6 130.5 1771 7 837 2050 8 150 2100 9 120 2140 10 175.5 2198.5 11 315 2303.5

In order to prevent water from running out at anytime of the day, we shift the line up and find the water supply line to be y = 264.71x + 100. The biggest difference between the daily consumption and daily supply gives the room we need for storage. From the chart, the biggest difference is 1650 gallons, which occurs at the 13 th hour. To be safe, we increase the volume a little and set the tank size to be 1700 gallons....
