Problem 3(30 points) Air is flowing over a flat plate at a velocity of 7m/s with a temperature of 20C. The plate has a width of 2m and a length of 8m with a temperature of 140C. Determine the rate of heat transfer from the plate if the air flows along the 8m side. The average temperature for the film is taken as 80C and the properties of air at the average temperature are as follows: a-) ( 15 points) Determine if the flow regime is fully laminar, fully turbulent or a combined type. b-) ( 15 points) Determine the rate of heat transfer from the plate
