Solve the following porblem:
Q: A horizontal 3-mm-thick flat copper plate, 1 m long and 0.5 m wide, is exposed in air at 27°C to radiation from the sun. If the total rate of solar radiation absorbed is 300 W and the combined radiative and convective heat transfer coefficients on the upper and lower surfaces are 20 and 15 W/(m2 K), respectively, determine the equilibrium temperature of the plate.
GIVEN
Horizontal, 1 m long, 0.5 m wide, and 3 mm thick copper plate is exposed to air and solar radiation
Air temperature (T?^?) = 27°C
Solar radiation absorbed (qsol) = 300 W
Combined transfer coefficients are
upper surface ( hu ) = 20 W/(m2 K)
lower surface ( h1 ) = 15 W/(m2 K)
ASSUMPTIONS
Steady state prevails
The temperature of the plate isuniform
