Question: 18.31 The convective heat-transfer coefficient between a large brick wall and air at 100F is expressed as h = 0.44 (T-Too)^ 1/3 Btu/h ft^2 F.

18.31 The convective heat-transfer coefficient between a large brick wall and air at 100F is expressed as h = 0.44 (T-Too)^ 1/3 Btu/h ft^2 F. If the wall is initially at a uniform temperature of 1000F, estimate the temperature of the surface after 1, 6, and 24 h.
