I don't feed my crew anything because they are not real...just entries in a database and lines of code. Which is probably a good thing because I have searched every inch of my virtual ship's interior and have not eno****ered a single virtual bathroom. If they were real and actually ate, I imagine that by now the interior would be filled with a lot of dead potted plants...
Weekly consumption = 166.6 tons per week
Per week per crew consumption = 0.111 tons per human crew per week
Is that correct? I find it difficult to believe that each crew member is consuming fifteen kilograms per person per day. Even if you include all of the water mass in food and premixed beverages (e.g. canned drinks), you still get less than half that at most even assuming four thousand kilocalories per day. Most edible/drinkable materials are not that much denser than water, and nobody is consuming a dozen liters a day unless it's mostly water and they are sweating extremely heavily.
