7-5) Water vapor at 250C is flowing with a velocity of 5m/s in parallel over a 2m-long flat plate where there is an unheated starting length of 0.5m. The heated section of the flat plate is maintained at a constant temperature of 50C. Determine (a) the local convection heat transfer coefficient at the trailing edge, (b) the average convection heat transfer coefficient for the heated section, and (c) the rate of heat transfer per unit width for the heated
