through radiation, calculate inside plate temperature

Consider the vertical rear window of an automobile that has a
thickness L= 9 mm and height H=0.5 m with heating wires that create
uniform volumetric heating. The window interior is exposed to
ambient air at 10°C and the window exterior to air at -10°C which
moves in parallel flow over the surface with a velocity of 20 m/s.
The surface temperature of the window exterior is 12°C.
Using the correlation developed by Churchill and Chu, find the

Pr=5.12
Nu=0.036×Pr^(1/3)×Re^(2/3):laminar flow
Nu=0.036×Pr^(1/3)×(Re^(0.8)-23200):turbulent flow

In a warehouse, a cold room that is maintained at
10oC has a wall made of two layers of
materials. The inner layer has a thickness of 2 cm and a thermal
conductivity of 0.1 W/mK. The outer layer, which is 4 cm thick, has
a thermal conductivity of 0.04 W/mK. The temperature of the outside
ambient is 30oC . The convective heat transfer
