Medium
For the same slab (thickness L, x=0 insulated, x=L at fixed T0, uniform heat generation S W/m³), the heat flux at x=L is
- A0
- BSL/4
- CSL/2
- SL
Explanation
Since x=0 is perfectly insulated, ALL the heat generated within the slab (total = S×L per unit cross-sectional area) must exit through the single open boundary at x=L. Heat flux at x=L = SL.
