Author's Notes
Information on how I came up with my numbers and sources
Fiefs and inhabitants
City: 100 fiefs, total 4.5 millions inhabitants (to compare, Paris population in 2019 = 2.1 millions)
Fief of Glass: 27 towers (close to the median for all fiefs), 45k inhabitants
Each tower = 50-100 floors, 1.7k inhabitants/tower, around 15 inhabitants per floors
Glasswork
Using as a model the British manufacture Cumbria Crystal makes hand-made lead crystal "using traditional skills, materials and heritage processes". They produce one ton per week.
Water
Using the Empire State Building as a compariosn for my towers: 102 floors, Floor area 2,248,355 sq ft (208,879 m²) floor area, 443.2 m high (1,454 ft)
A study in the US found that inpatient healthcare buildings were the most intensive users of water, averaging 50 gallons per square foot per year. Next are buildings like hotel averaging 42 gallons per square foot per year.
I have farming in my towers, which are going to use more water, but most plants take their roots directly under the city and so don't need additional water, so I'm using the 50 gallons per square foot per year.
That means that 1 tower use 101,175,975 gallons water per year = 1049 m3/day, and so all 27 towers use 28k m3/day.
Checking if the underground river can withstand 100 fiefs with similar needs, I use the [url:https://fr.wikipedia.org/wiki/D%C3%A9bit_de_la_Seine_%C3%A0_Paris]Seine[/rul] at Poissy as a model: average flow is 493 m3/s = 42.6 millions m3 per day, should be enough XD
Flour
In the Middle Age, to feed one active person for a day with bread as the main source of calories: one 2lbs whole wheat bread
Net yield in 1800-1849 for wheat was 23.16 bushes/acre.
A bushel of wheat = 90 one-pound loaves of whole wheat bread = 45 loaf of 2 lbs of whole wheat bread.
So to feed 1 person for 45 day = 60 pounds whole wheat flour, 1 person a year = 8.1 bushel of wheat or 486,67 pounds of flour, and for 45k people 1 year = 365k bushel of wheat = 21 900 000 pounds of flour = 9 934 tons flour
Wine
Using as a model Château Yquem, a very small winery with an extremely weak yield (average 9hl/ha), a good model for my Soulmates' wine which needs high magic concentration.
Château Yquem has 113ha (= 1.13km²) and makes 100k bottles/year.
The Empire State Building has an outside surface area of 8,094 m², so this is enough, however the entire surface woul dnot be covered in vine. I also wants the wine to be very exclusive, so I'm taking the Château Yquem values and hlafing them.
