Heat Transfer

No need for number, just theoretically

find surface temps Tz 7,¢ Ta in terms of o T, な- ア
Transcribed Image Text:find surface temps Tz 7,¢ Ta in terms of o T, な- ア
Expert Solution
Step 1

Heat diffussion equation is given by-

∇2T + qK = 1α∂T∂t

α=kρCpV=Thermal diffusivity

Since  steady state, hence ∂T∂t=0

First approximate the first order differentiation at intermediate points (L+1,0), (L-1,0)

∂T∂xL,0=∆T∆xL,0=TL+1,0-TL,0∆x

 

∂T∂x0,0=∆T∆x0,0=TL,0-TL-1,0∆x
