Thank you! Using the temperature of the Earth as the isothermal heat sink for that direction of radiation, I got the correct answer!
But, my problem with the polish plate still exists where I am getting a higher temperature than the black plate. The correct answer should be 285.06K. I added...
I am designing a fan blade which is attached to a generator. The unit will be submerged in water. The blade will be attached to the generator by a shaft. The device is semi-enclosed in a cylinder with the top and bottom open. The force of the waves will cause the propellor to spin.

Homework Statement
Two large thin aluminum plates, the first polished (emittance = 0.05 and the second painted black, are placed horizontally outdoors, where they are cooled by air at 283K. The heat transfer coefficient is 5 W/m^2-K on both the top and bottom. The top is irradiated with 750...
