Chapter 3, Problem 3.72P

The 150-mm-thick wall of a gas-fired furnace is constructed of fireclay brick k = 1.5 W / m K , ρ = 2600 k g / m 3 , c p = 1000 J / k g K and is well insulated at its outer surface. The wall is at a uniform initial temperature of 20°C, when the burners arc fired and the inner surface is exposed to products of combustion for which T = 950 ° C and h = 100 W / m 2 K .

(a) How long does it take for the outer surface of the wall to reach a temperature of 750°C’?

(b) Plot the temperature distribution in the va1l at the foregoing lime, as well as at several intermediate times.

The latent heat of fusion of seawater is approximately 300 kJ/kg, meaning that it takes 3x105 J to melt one kg of sea ice. The Arctic sea ice pack is reduced in thickness by approximately 20 cm (area average) each summer (from May to September, approximately 1x107 s). Ice has a density of roughly 1000 kg/m3. How much power per unit area (W/m2) is required to melt sea ice at this rate?
