Newton's law of heating equation
http://www.endmemo.com/physics/coollaw.php Witryna24 mar 2015 · Newton's law serves equally for cooling or warming situations: d T d t = k ( T e − T) The general solution is T ( t) = T e + ( T 0 − T e) e − k t; where T 0 = T ( 0) is the initial reading we are going to find In this case T e = 390 ∘ F is the oven temperature; so we can write T ( t) = 390 + ( T 0 − 390) e − k t

Witryna24 wrz 2024 · dQ is the heat transferred to the medium in the time interval dt. This is related to the heat capacity by $$ dQ=m C dT $$ where m is the mass of the cooling body and C is the heat capacity (in J/kg). By combining the two equations you will get a differential equation whose solution is the temperature variation in time, T(t). Witryna24 kwi 2015 · See also page 131 of the same book.
