Hot carbon dioxide exhaust gas at 1 atm is being cooled by flat plates as shown in Fig 3. The gas at 220°C flows in parallel over the upper and lower surfaces of a 2- m-1long flat plate at a velocity of 2 m/s. If the flat plate surface temperature is maintained at 80°C, de termine i. the local convection heat transfer coefficient at 1 m from the leading edge, the average convection heat transfer rate over the entire pl ate, and the total heat flux transfer to the plate. i. ii.

What are the differences between velocity boundary layer and thermal boundary layer? Discuss about both boundary layers including the characteristics, the profiles and factors affecting the boundary layers.
