A one-dimensional plane wall of thickness 2L=80 mm experiences uniform thermal generation of q= 1000 W/m^3 and is convectively cooled at x=±40 mm by an ambient fluid characterized byT infinity=20degreesC. If the steady-state temperature distribution within the wall is T(x) = a(L2-x2)+b where a=15oC/m2and b=40oC, what is the thermal conductivityof the wall? What is the value of the convection heat transfer coefficient?

Explanation:

Considering the one dimensional and steady state:

From Heat Conduction equation considering the above assumption:

      Eq (1)

Where:

k is thermal Conductivity

is uniform thermal generation

Putt in Eq (1):

Energy balance is given by:

    Eq  (2)

Putting x=L

From Eq (2)

it was a fall down when it happens

i lost in getting someone back.

i learned that people are really two-faced and no matter how angelic someone appears they always have a devil side and that you cant trust anyone anymore no matter how dear they are to you.

if your wondering who it waz it waz mah still miss her tho
