<strong>Life</strong> <strong>Support</strong> Design Rules of Thumb<br />
• A crew member requires 5 kg of consumables/day<br />
– ~1/2 water, 1/3 food, 1/6 oxygen<br />
– (including water in food) 77% H2O, 17% O2, 12% food<br />
solids<br />
– Dehydration reduces food mass by 2/3<br />
• Food solids produce about 5 calories/gm<br />
• Respiration produces about 3.4 calories/gm O2<br />
• Males need about 1/3 more calories than females<br />
– Or, males need 1/7 more than average, females 1/7 less<br />
– Males need one extra day/week of food, females one less<br />
