How to calculate time required for cooling

Web13 mei 2016 · We get numbers for how long it takes the metal bar to cool from 200 to 100 degrees Celsius, and we have to calculate how long it takes for the object to cool to 50 degrees. At first I thought of just using Newtons law of cooling (T (t)=T0+ (Ts-T0)e^ (-kt)), but I'm wondering if you can use this other way. Φ = ε σ A ( T m e t a l 4 − T a i r 4) WebSo if the cooling power is actually 1,5 W, the cooling time will be 1.45 Wh/(1.5-0.864)W= 2,28 h.
