Re: Fire Building Club
OK, so lets do the maths on this one:
Assmuning that the average person standing facing the fire is 1&1/2 ft wide plus an extra 6 inches to allow for the beer in one hand stance = 2ft space per person.
Allowing for a comfortable standing distance from the fire of 1 metre (3 or so ft):
6ft round fire: (6 + 3 +3) * 3.14 = 37.68ft. Based on the assumptions above, this allows for 15 people holding a beer in one hand and 3 holding a beer in each hand.
4ft by 8ft rectangle: 2 * ((4 + 3) + (8 +3)) = 36ft. Based on the assumptions above, this allows for 18 people holing 1 beer in one hand.
Now, in terms of effort:
The 6ft circle will require a moving of 28.64 square feet of earth 1ft deep.
The trench will require the moving of 32 square feet of earth 1ft deep.
In terms of beers in hand per square foot of earth to be moved:
Circle = 73.32% efficiency
Trench = 56.25% efficiency
