I just realized I made a small notation error on the Dutch oven briquette formula. I made it a little more simple.
Here is the final formula:
25n(t/100)=c
n=Total number of briquettes.
t=Outside temperature accounting for wind.
c=cooking temperature.
The formula is simple to understand and solve if you know how to do basic algebra. Let’s say you want to cook at 350F, which is common for Dutch ovens. Let’s say the temperature outside is 70F. Solving it would go as follows:
25n(70/100)=350
25n*0.7=350
25n=500
n=20
You will need 20 briquettes to cook at 350 when the outside temperature is 70F.
Another example with yesterdays math problem during the final formula experiment. Outside temp was 92F, and I wanted to cook at 350. Now the formula:
25n(92/100)=350
25n*0.92=350
25n=380.43….
n=15.21….
If the outside temperature is 92F and you wanted to cook at 350F, you will need about 15 briquettes.
This formula works. Now I need to figure out how to adjust it for different sized Dutch ovens. So far it works well with a Dutch oven that is 10 inches in diameter.
I got to figure out how to adapt it to bigger or smaller Dutch ovens now.
