For the above left surface of the copper plate (k = 400 W/m C) the surface absorbs heat flux from the sun of 200 W/m2. The surface also convects to the adjacent air, which is at 25 C. The convective heat transfer coefficient is 5 W/m2 C. What is the boundary condition equation for the left surface, whose temperature is Tleft C.

For the above left surface of the copper plate (k = 400
W/m C) the surface absorbs heat flux from the sun of
200 W/m2. The surface also convects to the adjacent
air, which is at 25 C. The convective heat transfer
coefficient is 5 W/m2 C. What is the boundary
condition equation for the left surface, whose
temperature is Tleft C.
