Aduct with a triangular cross section has one of its sides heated by a heater at 1.0 kw/m" rate. the heated surface has emissivity of 0.75. as a result, the two other surfaces are heated and maintained at 227 ? . the duct is very long, thus, the radiation exchange through the open ends is minimal and can be neglected. if the three sides of the cross section are each 200 cm long, determine the temperature of the heated surface (surface 1).
