Where’s the picture of the problem
Answer:
Fourier's laws
Explanation:
The problem can be solved if Fourier's laws for conductivity are applied as well,
(1)
where
A = heat transfer area (m2, ft2)
k = thermal conductivity of the material (W/m.K or W/m oC, Btu/(hr oF ft2/ft))
ΔT = temperature difference across the material (K or oC, oF)
s = material thickness (m, ft)
The thermal conductivity of concrete is k= 1.7
Since
1 dollar = 5 Kilowatt hours or 5000 watthours so
Time for 1 dollar = 5000/1256.64 = 3.978 hours or 3 hours 58 minutes
