The initial temperature of a rod 0 x l thermally insulated along the surface equals U0 = const; and a constant temperature is maintained at its ends u(0; t) = U1 = const; u(l; t) = U2 = const; 0 < t < 1: Find the temperature u(x; t) of the rod for t > 0; determine also the steady-state temperature u(x) = lim t!1 u(x; t):

Very easy to follow these lectures, but is it possible to have an order for the heat transfer lectures ? Thanks

The "Conduction Equation Derivation" video does a MUCH better job of explaining boundary conditions.

i.e. this video sucks? i agree. will try your suggested alternative.

what pages in the NCEES reference manual can I find these eqns? I am looking through the thermodynamics and fluid mechanics sections but can't find these equations...

At 4:17, why are you using q and not Q? Isn't q heat flux? So shouldn't it be q=-k(dT/dx)?

q is not heat flux, it is heat flow rate . Unit of q is watt(j/s). you can use dimensional analysis to check it

+fastertbird those were the boundary conditions set for example 2 it is the condition that as X→L The rate of convective heat transfer from the system is equal to the net rate of conductive heat transfer
