Anyone know what the constant (k) value for 5 gallons of beer in a plastic bucket is ?
Newton's Law of Cooling equation is:
T2 = T0 + (T1 - T0) * e(-k * Δt)
where:
T2: Final Temperature (C)
T1: Initial Temperature (C)
T0: Constant Temperature of the surroundings (C)
Δt: Time difference of T2 and T1 (hours)
k: Constant to be found
I reverse engineered a rough value of 0.1. This was based on observed temperatures and times. I read a dead human body has a K value of 1.7. Therefore, 5 gallons of beer =/= dead body!
Is this consistent with your observations?
