Aplane slab absorbs neutrons from a nuclear reactor and experiences non-uniform internal heat generation something like q’’’(x)=q0exp(-5x/l). cooling is provided at x=0 by convection to a fluid at t∞ = 50 c, and the surface temperature is maintained at t(0) = t0. the back side of the slab, at x=l, is insulated. use an energy balance to find the value of the heat transfer coefficient required. use these numbers for the parameters: q0=1.4×107w/m3, t0=107 c, and l=100 mm. the thermal conductivity of the material is k=40 w/m-k.
