A plastics plant manufactures larges pieces of plastic by continuously extruding thin sheets.As the sheets flow out of the extruder, they are cooled via forced convection and radiation.The plastic sheets are 1 mm thick, 1 m wide, and leave the extruder at a rate of 9 m/min.A fan blows air over the top and bottom surface of the sheet during the first meter after thesheet leaves the extruder. The fan accelerates the air to 3 m/s and the air is known to be at27°C at the fan outlet. At the exit of the extruder, the plastic is at 90°C. The plastic isestimated to have an emissivity of ? = 0.9 and the general surroundings are at 20°C. A) Determine the rate of heat transfer via convection and radiation from the 1-m-longsection of the plastic sheet that is being force cooled. take the surface temperature to be 90°C overthe entire section of interest.
