Air flow along a length of a 50x50cm square heated flat plate is in a large room, the plates surface is at a uniform 127degC. Free steam conditions are 15m/sec and 27 deg C. surrounding walls are uniformly at 20 deg c. the surface of the plate has an emissivity of .6. the critical renolds number is 5x10^5 for the flow. Find the heat transfer rate rom one side of the plate in watts.
