A slab, 0 ≤x≤ L, is initially at zero temperature. For times t > 0, heat is generated in the slab at a constant rate of go (W/m³), while the boundary surface at x =0 is kept insulated and the boundary surface at x = L is kept at zero temperature. Obtain an expression for the temperature distribution T(x, t) in the slab (i) using the Laplace transform technique that is valid for all times and (ii) an approximation that is valid for very small times.

Transcribed Image Text:A slab, 0 ≤ x ≤ L, is initially at zero temperature. For times t > 0,
heat is generated in the slab at a constant rate of go (W/m³), while the
boundary surface at x = 0 is kept insulated and the boundary surface at
x = L is kept at zero temperature. Obtain an expression for the temperature
distribution T(x, t) in the slab (i) using the Laplace transform technique
that is valid for all times and (ii) an approximation that is valid for very
small times.
