Hot carbon dioxide exhaust gas at 1 atm is being cooled by flat plates. The gas at 220°C flows in parallel over the upper and lower surfaces of a 1.5-m-long flat plate at a velocity of 3 m/s. If the flat plate surface temperature is maintained at 80°C, determine

(a) The local convection heat transfer coefficient at 1 m from the leading edge,

(b) The average convection heat transfer coefficient over the entire plate,

(c) The total heat flux transfer to the plate.
