WebTemperature (T) = 80.0 K. Specific heat (c) = 1676 KJ. Now we have to convert the specific heat into Joules because it is in Kilojoules. So, the conversion is like this. 1 KJ = 1,000 J. So, 1676 KJ = 1,000 × 1676 = … WebApr 24, 2015 · Insulated means that the normal derivative of the heat distribution at the boundary is 0. This is because heat flows according to the temperature gradient; it flows from hot to cold. So that means you want R ′ (1) = 0. In terms of S(r) = (rR(r)), that gives d dr(1 rS(r)) r = 1 = 0, − S(1) + S ′ (1) = 0. The final equations for Q(t) and S ...
WebHere , we applied heat equation. The heat equation is given by: k ⋅ ∂ A 2 A 2 2 2 u / ∂ x A 2 = ∂ u / ∂ t.
