Extracted text: An oil radiator has an outside surface area of 0.18 m2 and operates at a surface temperature of 85 degree Celsius. If the oil radiator behaves as a black body and the Stefan-Boltzmann constant value is equal to 5.67 X 10-8 W/(m²-K4), calculate the radiation heat flux at the surface of the radiator.
